Tapejara

Tapejara is a genus of tapejarid pterosaur from the Early Cretaceous period, known from fossils found in the Santana Formation of northeastern Brazil. The genus was named for its distinctive cranial crest and is represented by at least one species, Tapejara wellnhoferi, described in the early 1990s. Fossils date to roughly 112 million years ago, during the Aptian stage, making Tapejara one of the better-documented crested pterosaurs from Gondwana.

Anatomically, Tapejara fell within the tapejarid family, which is characterized by elongated skulls and prominent head crests. Tapejara itself possessed a relatively short, broad beak and a large, elaborate cranial crest that arose from the skull and could extend backward over the head. The jaws were either toothless or bore only a few teeth toward the tip, a feature common among many tapejarids. The combination of a broad beak and a striking crest makes Tapejara one of the most recognizable pterosaurs from its formation.

Ecologically, the Santana Formation represents a lush, inland environment with forests and lakes. Based on crest morphology and beak structure, Tapejara is interpreted as having a frugivorous or omnivorous diet, possibly feeding on fruit, seeds, or vegetation, with crests likely used in display or intraspecific signaling rather than flight.

Taxonomically, Tapejara is placed in the family Tapejaridae, a group of crested, short-skulled pterosaurs that were common in Early Cretaceous South America. Its discovery has contributed to understanding the diversity and biogeography of pterosaurs in Gondwana and the evolution of cranial display structures in pterosaurs.
