New Tapejarid Pterosaur Species Identified in England
Paleontologists discover Hintighernia edingerae, challenging previous assumptions about tapejarid pterosaur geographic origins.
1Historical Specimen Reclassified
Paleontologists identified a new genus and species, Hintighernia edingerae, from a specimen originally housed in the Sedgwick Museum of Earth Sciences. First described in 1870, the fossil was previously misassigned to Ornithostoma sedgwicki. Researchers now argue that the original name should be restricted to a different chaoyangopterid pterosaur species instead.
2European Evolutionary Roots
The discovery of this species in Britain suggests that tapejarids, long associated primarily with Cretaceous deposits in Brazil, may have deeper roots in Europe. This finding positions Europe as a potential center of early tapejarid radiation, influencing the evolutionary history of related groups found in eastern Asia and South America.
3Anatomical and Ecological Traits
Tapejarids are recognized by their short, downturned snouts and sometimes prominent premaxillary crests. Scientists suggest these pterosaurs were ecologically atypical for their time, potentially exhibiting omnivorous or herbivorous feeding habits. The new genus Hintighernia edingerae lived during the Cretaceous period, specifically between 105 and 100 million years ago in Britain.
4Digital Braincase Reconstruction
Researchers utilized micro-CT scanning to digitally reconstruct the braincase of Hintighernia edingerae. The resulting endocast, a model representing the space once occupied by the brain, shows striking similarities to Tapejara wellnhoferi. These neuroanatomical parallels indicate a close evolutionary kinship, though further phylogenetic studies are required to confirm these specific relationships.
5Cambridge Greensand Diversity
The Cambridge Greensand Member has yielded over 2,000 pterosaur specimens, providing a rich dataset for analysis. Beyond the new genus, researchers identified a snout tip fragment labeled as cf. Hintighernia. Additional neck vertebrae and arm bone segments suggest the presence of at least three distinct azhdarchoid species within this specific geological layer.
6Biogeographical Dispersal Patterns
The study proposes that Europe served as a critical hub for early tapejarid diversity. Dispersal routes likely extended through North Africa, potentially supported by the Eurogondwana hypothesis. This model explains how the group may have radiated from Europe to reach diverse environments across the globe during the Cretaceous period millions of years ago.
7Reassessing Existing Collections
The research team conducted a comprehensive reassessment of various pterosaur specimens previously collected from the Cambridge Greensand. By distinguishing between different azhdarchoid forms, they identified a minimum of four distinct types. This rigorous re-examination highlights the importance of revisiting museum collections to clarify the complex evolutionary history of ancient flying reptiles.
8Scientific Publication Details
These findings were formally reported in the Zoological Journal of the Linnean Society by lead researcher Rubi Pêgas and colleagues. The study provides essential comments on neuroanatomy and the broader biogeography of the tapejarid group. This work underscores the ongoing necessity of modern analytical techniques in interpreting long-held paleontological fossil records.
