New Filter-Feeding Pterosaur Discovered in Santana Group

A new filter-feeding pterosaur species, Bakiribu waridza, has been discovered in the Santana Group of Northeast Brazil, representing the first archaeopterodactyloid from this formation and providing insights into the evolution and paleobiogeography of ctenochasmatids in Gondwana. The specimen, preserved as a regurgitalite, exhibits unique dental features, including dense, elongated, and subquadrangular teeth, and suggests a complex trophic interaction involving likely predation by spinosaurid dinosaurs.

Ancient Marine Reptile: A Prehistoric Filter-Feeder

Fossils of Hupehsuchus nanchangensis, an extinct marine reptile closely related to ichthyosaurs, have been discovered in China, revealing that these creatures were filter feeders similar to modern baleen whales. Analysis of the skulls of two specimens showed structures that allowed them to scoop up water and sift out prey. The skull structure of Hupehsuchus suggests it independently evolved some form of baleen, with a long, flexible snout and grooves along the jaws. This discovery indicates that filter feeding evolved as early as 250 million years ago, during the Triassic Period. The rapid evolution of these marine reptiles had a significant impact on marine ecosystems during a time of turmoil.

Ancient Chinese Fossil Unveils Reptiles' Whale-Like Filter Feeding in Prehistoric Era

A 250-million-year-old reptile fossil, Hupehsuchus, discovered in China, reveals that it used a whale-like filter-feeding method, providing insight into early marine ecosystems. The ancient reptile had soft structures, an expanding throat region, and baleen whale-like structures to filter food items. The discovery of these adaptations in an early marine reptile sheds light on the rapid re-population of the oceans after the end-Permian mass extinction. The Hupehsuchus skulls exhibit grooves and notches similar to those found in baleen whales, suggesting independent evolution into some form of baleen.

Ancient Marine Reptile Unveils Whale-Like Filter-Feeding

A new fossil discovery in China reveals that the marine reptile Hupehsuchus, which lived 250 million years ago, had adaptations for whale-like filter feeding. The skull of Hupehsuchus shows soft structures that allowed it to engulf water containing prey and baleen whale-like structures to filter food. The discovery suggests that these reptiles independently evolved a form of baleen, similar to modern baleen whales. This finding sheds light on the rapid re-population of the oceans after the end-Permian mass extinction and the ecological changes that occurred during the Early Triassic period.
