Originally Published 2 months ago — by Nature
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.
