Sento-me, a horas improvaveis, numa cadeira desconfortavel do Shuler Museum e reparo no que tenho em volta. Para alem dos fosseis empilhados em armarios de metal, para alem dos cranios impressionantes de fitossauros, para alem dos esqueletos articulados de criaturas bizarras... vejo discussoes inflamadas sobre os detalhes da Evolucao, vejo ideias e resolucoes interessantes baseadas nos mesmos fosseis bizarros, vejo horas que escoam num domimgo lamacento no topo de uma arriba, vejo os olhos que brilham quando alguem diz no campo "Vejam so o que encontrei!", oico o martelo percurssor do laborioso preparador... e, penso... Caracas, por mais que quisesse nunca conseguiria encontrar uma profissao como esta porra...
Todas as horas que dispendi a tirar fotocopias de artigos obscuros e que nao serviam para nada, que dispendi a encharcar as botas de lama e voltar a casa com meia duzia de pedras no bolso, que dispendi a fritar os olhos a frente do computador aguardando que ele me desse resultados desoladores... todas essas horas, nao as dou a ninguem.
'As vezes ate me custa mesmo perceber como e' que alguem pode gostar de outra coisa senao paleontologia... quem e' que gosta de metalurgia, bolas? De contabilidade? Tenho de me contorcer para compreender isso, sim, eu sei, gostos nao se discutem...

Investigadores do Museu da Lourinhã em peso em África
Ricardo Araújo e Rui Castanhinha vão para Moçambique; Octávio Mateus para Angola... parece que aprendemos bem a lição de Louis Jacobs no seu livro "In the Quest for African Dinosaurs". De facto, a paleontologia africana é um mundo por descobrir e há mais de meio século que algumas formações não são olhadas com o olho "clínico" de paleontólogos. Alea jacta est! Aqui vamos nós!

Entrevistas aos bochechos: 10ª pergunta ao Paul Upchurch
RA: A random question now, but I think it is interesting to think about this sort of things, can vertebrate paleontology be a profitable science?
PU: I think you can argue it already is in some ways. It is quite clear that the general public are interested in dinosaurs in particular, but paleontology in general. So I think there are a number of roots through which paleontology can be economically viable. There is obviously museum work, educational work, work with the media, or, manufacturing casts for museums. In the States, for example, people actually pay in order to dig dinosaurs. There are a number of ways in which the subject canearn money… and I’ve just mentioned a few of them, there are things like writing books and so on. But I think it is absolutely crucial that governments continue to fund paleontology because it is a fragile science. It is one that we do out of interest, rather than something that is going to cure cancer. It has two important contributions that mean the government should want to fund it: the first one is educational, particularly if we can attract children to science… they don’t have to become paleontologist, they can become doctors or engineers. But, if we can inspire them to be interested in science in first place, I think that paleontology and particularly dinosaurs are good ambassadors.
Entrevistas aos bochechos: 8ª pergunta ao Paul Upchurch
RA: Now, just a general broad question: what would you change in the Vertebrate Paleontology community? What do we need? What is still lacking in our community?
PU: Across the community as a whole we’re pursuing very interesting lines of research, but my personal view is that there are two or three things that we could change a little bit. One is there is still a tendency to think that the final goal of a publication is to produce a cladogram, and I think that is a good starting point… but you have to use it to investigate macroevolutionary issues. The second thing is that we need to become more quantitative in our approaches, we still tend to be viewed by non-paleontologists – perhaps quite unfairly – as a hand-waiving area…one that has a lot of speculation and not does not rely very much on facts or analysis. We actually have the ability to analyze data in a quantitive/statistical fashion, we need more of that… and some of our invertebrate paleontology colleagues are leading the way. The final thing that I think we need to change, which is much closer to my particular interests, is that nearly all the papers that discuss biogeography are essentially speculative. They look at the fossil record, they see the various organisms at various places and various points in time, and they build a story around them. This is not adequate testing of the hypothesis. My view is that we need move from, what is called in philosophical terms, the narrative/story-telling phase. What we need to move into is a more analytical phase, where we actually reject hypothesis or verify them by getting large amounts of data and analyze it quantitatively. The same reasoning holds true for all aspects of paleobiology: we need to become more quantitative in diversity, evolution and things like that.

Entrevistas aos bochechos: 7ª pergunta ao Paul Upchurch
RA: Going back a little bit on the sequence of questions, I think that your work on area cladograms and biogeography gives very interesting support where to look for dinosaurs and pursue new taxa. First of all, do you agree with this? And second, if you would have to use this data, where would you work for new taxa?
PU: The biogeographic approach I use, they provide some explanation why some types of dinosaur appear or do not appear in certain places and certain points in time. But of course, that can always be falsified by new discoveries. What I think that is more relevant to directly finding or targeting new localities is the work that my student and in conjunction with me is doing, we’ve built an almost comprehensive database of sauropod occurrences. So what that allows is an analysis like: do sauropod appears in certain types of sediments more often than others; are there areas of the earth that have produced poor quality sauropod material or good quality sauropod material? So I think large scale database are probably the future to a scientific approach to know where to go to collect new material.

Entrevistas aos bochechos: 6ª pergunta ao Paul Upchurch
RA: So, the other area of your research is to look specifically at the evolution of sauropods. Could you outline in broad terms the evolution of the group?
PU: Essentially, they appeared in the Late Triassic; at that stage we call them sauropodomorphs. They are generally small animals, 1-2meters long, they are bipedal… but they still show one or two key features of the sauropodomorphs: relatively long neck, a small head on that neck and some changes to the jaws and teeth, which is suggesting that they are changing from carnivores to omnivores or omnivores to herbivores. Then in the Jurassic, those small forms disappear and we see a trend towards a larger and larger body size, quadrupedality, elongation of the neck and further modifications of the skull. So we get a radiation of the true sauropods, which by the Jurassic have achieved gigantic body size (20-25m). We also see a radiation of many types of sauropods: diplodocoids, early titanosaurs, brachiosaurs, and so on… Then, at the Jurassic/Cretaceous boundary there seems to be a crisis, about 80% of the sauropods go extinct, mainly the ones with the very large spoon-shape teeth. In the Late Cretaceous, sauropod faunas are dominated by the titanosaurs. There are other types like the rebbachisaurs – that were unusual types of diplodocoids – but they radiate again, the also become very diverse. By the end of the Cretaceous there were about 50 or 60 titanosaur genera, which is about one third of sauropod diversity. At the K-T boundary all of those disappear.

Entrevistas aos bochechos: 5ª pergunta ao Paul Upchurch
RA: In which sense are dinosaurs the best clade to test this sort of tools?
PU: I don’t think they are the best clade, but they are one of the best clades. They are a good place to start because they have a relatively rich fossil record, they have a long fossil record – that spans several geographical events –, they have a virtually global distribution; so they can pick up episodes like the break-up of the continents, changes in sea level. And, of course, relative to other groups they are intensively studied; there are far more people working with dinosaurs in the Mesozoic than there are, say, on crocodiles or lizards. But, I think, the best way to analyze biogeographic history is to take multiple groups, ideally groups that have different groups that have different body sizes and different physiologies. If we show that flowering plants, insects, small mammals and dinosaurs are all showing the same patterns, that reinforces the evidence that, despite differences, in the way they live these groups are all affected to the same geographic events. So, I started with dinosaurs because that is my strength, that is my area of interest… but I am interested expanding the work to other groups as well, or, encourage my colleagues to apply the same methods.
quinta-feira, maio 07, 2009
Entrevistas aos bochechos: 4ª pergunta ao Paul Upchurch
RA: Yeah, one of the methodological tools that came out from this sort of ideas were area cladograms, wasn’t it?
PU: Area cladograms are an older idea, they go back to the original work done in the 1970’s. But, there is a fundamental problem with an area cladogram which is that by definition a cladogram shows branching structure. And that is fine when you are dealing with organisms that have a nice branching structure phylogeny. The problem is that an area cladogram isn’t describing the evolution of organisms, it is describing the relationships between geographic areas. And geographic areas do not have to obey a branching pattern. They can break up from each other, but they can also collide…they can reconnect. That means that the history of geographic areas is a complext network and not a simple branching pattern. So, the area cladogram by itself is a good idea, but not sufficient to describe biogeographic history. Where the time slicing idea comes in is that you continue to produce area cladograms, but each area cladogram is different for each point in time. By looking how each area cladograms change from each point in time, to the next, to the next, to the next…those changes tell you about the network-like history
Between the areas. So, to give you an example, in the Early Cretaceous we find that South America and Africa cluster together in the area cladogram, we’d say Australia would be more distant – as it was – and then in the Late Cretaceous we find actually that South America and Australia are clustering together with Africa being further away. What we see is a change in the area cladogram structure and, what that means is that between the Early Creataceous and Late Cretaceous that has been some change in biogeography, that cannot be expressed by one area cladogram but by two in sequence. And so, what we are really doing is trying to express this really complex network of area relationships as a series of area cladograms, rather than one area cladogram

Entrevistas aos bochechos: 3ª pergunta ao Paul Upchurch
RA: But isn’t it somehow stratocladistics… isn’t it the same?
PU: No, because in stratocladistics what you do is, when you are building your evolutionary tree you add information on the stratigraphic positions of the organisms and that has an influence on the tree. What I propose is that you keep building evolutionary trees in a conventional manner – using morphological characters or molecular characters if you are working with living organisms. Now, once you have that evolutionary tree you should is analyze biogeography within a certain defined time window. So if I’ve built an evolutionary tree of all dinosaurs in the Early Cretaceous, what I should do is then remove any dinosaurs that are not from the Early Cretaceous. And although that sounds like a bad idea – it sounds like you are throwing away data – the good thing about it is that it helps us focusing on the patterns that happen in the Early Cretaceous. If I can give you an analogy: if I listen to a music and ask you to describe that piece of music in mathematical terms; for one piece of music that might be relatively easy… if I play two pieces of music at the same time it starts to get a little bit confusing, if I play a thousand pieces of music it is almost impossible to understand anything… the problem is if you take a very large dataset. Let’s say all vertebrates from the Triassic up to the present, there are so many different patterns that are so different from each other, they conflict. The idea is to slice in narrow chunks of time, and analyze each of those for biogeographic patterns.

Entrevistas aos bochechos: 2ª pergunta ao Paul Upchurch
RA: Another thing I would like to know a little more about is that in 2005 you’ve published a paper proposing a new paradigm. What does that paper entail?
PU: You are talking about the new biogeographic paradigm… Well, the initial idea was published in 2001, but I’ve published a series of papers since then. Essentially the idea is that amongst biologist working in animals, over the last 30 years or so, there was a growing tendency to analyze biogeography in a more statistical fashion. The information that is required to understand that are evolutionary relationships and the geographic localities of the organisms. Essentially it is cladistics plus biogeography. The problem that I and my colleague Craig Hunt proposed originally in 2001, is that it doesn’t take time into account… I think the reason why we haven’t taken the temporal or stratigraphic distribution of organisms into consideration previously is precisely because these methods used previously were only used by people working on living animals, and therefore they only have one time to worry about, which is: now! But as soon as you look at paleontology, you should ask the question: Should I take data from all the Mesozoic? Or just from the Jurassic, or Cretaceous and so on… What we realized was that the geographic distribution of organisms change through time. The patters we get in the Jurassic are not necessarily the patterns we get on the Cretaceous and so on…We realized that paleontology actually played a key role in historic biogeography, whether you are working on living animals or extinct animals. You need to take into account the time of the events, because otherwise you end up with serious problems…

Entrevistas aos bochechos: 1ª pergunta ao Paul Upchurch
Lamento estar em Inglês, assim que fôr possível traduzirei para Português.
RA: As a first question I would like you to describe a little bit your work… Ongoing projects… and so on…
PU: My two main interests are essentially: the evolution of sauropods and the biogeography of particular dinosaurs, but also of other terrestrial animals in the Mesozoic. Of course, the two go together very nicely because by working in dinosaurs I gain data for other animals. The kinds of things I’ve been working on lately include coming to Portugal to collect data and that is part of a wide project. I’ve received some funds either from Banco Santander and also from the British Paleontological Association, and that money will allow myself and my students to go to Portugal, Spain, Germany and North America to collect data on sauropods, partially for taxonomic work but for my particular case to draw a very large phylogeny on sauropods, probably about 120 to 130 species, which is about two thirds of the current known diversity. That is the bigger picture, and once I have that evolutionary tree I will be using it to biogeography, diversity, issues to do with body size evolution…

Nova Publicação: Colecção de Fósseis de Vertebrados de Sir Alfred Leeds

A colecção de fósseis de vertebrados que está no National Museum of Ireland é relavante sob o ponto de vista histórico mas também científico. Acontece que no final do século XIX um senhor chamado Alfred Leeds que vivia no Peterborough District começou a acumular uma importantíssima colecção de fósseis de vertebrados a partir do seu barreiro. Durante mais de vinte anos Alfred Leeds (principalmente, se bem que inicialmente ajudado pelo seu irmão Charles) acumulou uma quantidade absolutamente impressionante de fósseis de uma inestimável riqueza científica. Desde plesiossauros, passando por crocodilomorfos, e por peixes gigantes como o Leedsichthys. A colecção em Dublin é uma fracção representativa do que existiu na formação de "Oxford Clay", onde o barreiro se inseria. Por outro lado, a Colecção de Alfred Leeds no National Museum of Ireland é um marco importante na história da própria colecção; assinala o momento em que Alfred Leeds começou a dispersar, vendendo, fósseis por todo o mundo. Hoje em dia a colecção de Alfred Leeds está em Uppsala (Suécia), Estados Unidos, vários museus de Inglaterra, etc. A maior parte dos fósseis estão no Hunterian Museum, mas os melhores espécimes encontram-se no The Natural History Museum, London.
À parte disto, este estudo foi extremamente interessante de se realizar. Não só ficámos a saber um pouco mais sobre uma colecção extremamente rica, mas também tive o prazer de trabalhar com um dos maiores especialistas na história da Colecção: Jeff Liston e com o meu colega e amigo Adam Smith. É um trabalho que merece uma leitura por parte daqueles que se importam com o híbrido que resulta da paleontologia pura e a história!

Paleontólogos históricos II: Gideon Mantell
Mantell ficou famoso por ter sido ele a estudar um dos mais antigos registos de dinossauros: o Iguanodon, do Cretácico inferior de Inglaterra. Este dinossauro foi assim chamado pela forma característica dos seus dentes fazendo lembrar os das iguanas aos olhos do paleontólogo. Na verdade, Mantell era médico, mas dedicava-se à história natural por prazer simplesmente. Curiosamente, o Iguanodon foi entretanto descoberto em muitas outras localidade da Europa, nomeadamente na Bélgica nas minas de carvão de Bernissart (que deu origem ao nome espécie Iguanodon bernissartensis)de onde foram recolhidos inúmeros indivíduos; mas também em Portugal (descritos na monografia de Sauvage 1897-98) e na Ásia (Iguanodon orientalis).
Foi na sua publicação "Notice on the Iguanodon, a newly discovered fossil reptile, from the sandstone of Tilgate Forest, in Sussex".

Homenagem a Choffat

Paul Choffat foi o verdadeiro pioneiro da Geologia de Portugal. Foi ele que esboçou os primeiros cortes geológicos, foi ele que interpretou as primeiras formações, foi ele que recolheu os primeiros fósseis e o seu legado é ainda hoje uma preciosa fonte de informação. É certo que outros antes dele também fizeram um trabalho meritório na Geologia de Portugal, mas é - sem margem para dúvidas - o seu trabalho o mais influente entre os pioneiros.
A FCT/UNL decidiu também homenagear o seu trabalho, clicar aqui.

Paleontólogos Pioneiros: Henri-Émile Sauvage (1842-1917)
O zoólogo francês Henri-Émile Sauvage (1842-1917) foi o primeiro a publicar um artigo científico citando a ocorrência de dinossauros em Portugal. Embora tenha desenvolvido sobretudo trabalho na ictiologia, os peixes fósseis devem ter sido a ponte para o seu interesse na paleontologia e nos dinossauros.
Sauvage é autor de, pelo menos, 50 artigos científicos de
H.E. Sauvage, Les crocodiliens et les dinosauriens des terrains Mésozoïques du Portugal, Bull. Soc. géol. France 24 (1896) 46–49.
