2008-12-03 – Un nuovo Pterosauro dal Brasile (Lacusovagus, Pterosaur)

Un paleontologo inglese, Mark Witton, ha riconosciuto una nuova specie di Pterosauro analizzandone i resti conservati in un museo in Germania

Il nuovo genere è stato nominato Lacusovagus, appartiene ad una famiglia i cui appartenenti erano stati ritrovati solo in Cina, e sarà descritta sul numero di Novembre di Palaeontology.

New flying dinosaur species found by British scientists

A new species of pterosaurs which had a wingspan 16ft wide has been uncovered by scientists – the largest of its kind to ever be found.

Mark Witton, a researcher at the University of Portsmouth, was able to estimate from a partial skull fossil that the pterosaur would have had a wingspan of five metres (16.4ft) and would have been more than one metre (39 inches) tall at the shoulder.

The fossil is the first example of a chaoyangopteridae, a group of toothless pterosaurs, to be found outside China and is the largest one ever discovered.

Mr Witton said: “Some of the previous examples we have from this family in China are just 60 centimetres (2ft) long – as big as the skull of the new species.

“Put simply, it dwarfs any chaoyangopterid we’ve seen before by miles.”

Mr Witton has christened the new species Lacusovagus, meaning lake wanderer, after the large body of water in which the remains were buried.

He was asked to examine the specimen, which had lain in a German museum for several years after its discovery in the Crato formation of the Araripe Basin in north east Brazil, an area well known for its fossils and their excellent state of preservation.

He said this fossil was preserved in an unusual way, making its interpretation difficult.

He explained: “Usually fossils like this are found lying on their sides but this one was lying on the roof of its mouth and had been rather squashed, which made even figuring out whether it had teeth difficult.

“Still, it’s clear to see that lacusovagus had an unusually wide skull which has implications for its feeding habits – maybe it liked particularly large prey.

“The remains are very fragmentary, however, so we need more specimens before we can draw any conclusions.”

He added: “The discovery of something like this in Brazil – so far away from its closest relatives in China – demonstrates how little we actually know about the distribution and evolutionary history of this fascinating group of creatures.”

Mr Witton’s findings were published in the journal Palaeontology in November.
