Tapejara inhabited a shallow basin environment, from which numerous specimens of aquatic animals like fish and turtles have also been recovered, as well as several other pterosaurs, including fellow tapejarids Thalassodromeus, Karirdraco, and Tupuxuara, as well as the anhanguerids Anhanguera and Cearadactylus and the large ornithocheirid Tropeognathus. However, these two species would later go on to be reclassified as their own genus, Tupandactylus.

In the following years, two new species would be assigned to Tapejara, T.

wellnhoferi and was placed alongside Tupuxuara within the newly-defined Tapejaridae, a group of Azhdarchoid pterosaurs known to possess large, bony crests extending from their snouts. Hailing from the Early Cretaceous Romualdo Formation of Brazil, Tapejara was described as a new genus in 1989 under the species T.
