Abstract
A new pterosaur specimen comprising a partial skull
and associated postcranial elements from the Lower
Cretaceous Wessex Formation of Yaverland, Isle of
Wight, southern England, is assigned to a new genus
and species of ornithocheirid pterosaur,
Caulkicephalus trimicrodon gen. et sp. nov., based on
several unique features including a heterodont
dentition in which the fifth, sixth and seventh teeth
are reduced in size compared with those at positions
1?4 and 8?9; the presence of a frontoparietal crest
and maxillopremaxillary crest that do not unite over
the antorbital fenestra or cranium; a palatal ridge
that extends no further forward than the eighth to
ninth tooth pairs. The new taxon is the second species
of pterosaur from the Wealden Group of the Wessex
Basin.
