5 miles south of Haslet near Fort Worth, Texas, fossils of an ankylosaurid were excavated from strata of the upper Albian rocks from Lower Cretaceous in the Pawpaw Formation.

[1] Vickaryous et al. (2004) and Coombs (1995) describe Texasetes as having a horizontally oriented ilium, an imperforate acetabulum, and "characteristically ankylosaur scapula morphology, including a prominent acromion and prespinous fossa.

This led Coombs to speculate that the individual had died on the shore or in an inland river and had been flushed out to sea, decomposing and losing many of its elements like the distal limbs.

Additional evidence comes in the form of paleo ecology, with nodosaurids and basal ankylosaurs being more commonly found in fluvial or marine sediments than ankylosaurids.

[6][1] Coombs (1995) diagnose Texasetes as having a horizontally oriented ilium, an imperforate acetabulum, and "characteristically ankylosaur scapula morphology, including a prominent acromion and prespinous fossa.
