Indet. giant pterosaurs Martill et al, 1996
Wingspan
>9metres (30 feet)
Stratigraphy
Vectis Formation
Lifestyle
Unknown. It is believed that large pterosaurs were mainly marine, living a lifestyle like albatrosses, and would therefore have eaten fish. As we have no good information about these specimens, it may not be the case...

Description of Material

Platypterygius is a toothed ichthyosaur that would have lived in deep waters, hunting squid, ammonites and maybe small plesiosaurs. Ichthyosaurs are known to have produced live young.

Description of Material

(Don't understand all the terminology? visit the Glossary)

Platypterygius is known on the Isle of Wight by several vertebrae, so may belong to another genus (see here). The snout relatively short and expanded, and the maxilla is also relatively short. The external nares are bordered by the lachrymal, nasal, and premaxilla. The anterior flipper has seven or eight digits. The lageniform and pisiform rarely extend to the distal humeral epiphysis, and contact with the latter is weak.

Platypterygius is a bit of a wastebasket taxon, into which all Cretaceous ichthyosaurs are placed. Whether the Isle of Wight Platypterygius is actually Platypterygius remains to be seen...
