Texasetes

. 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. The fossils would later become the holotype (USNM 337987) of Texasetes, consisting of a skull fragment, 2 teeth, 5 cervical centra, 3 sacral centra, 16 caudal centra, partial scapulacoracoids, fragmentary pelvis, humeri, femora, tibiae, proximal ulnae, proximal radii, left metacarpal IV, left metatarsal IV, 3 phalanges, 2 unguals, and several osteoderms. These remains had initially been labeled as those of a sauropod, but were many years later recognized as ankylosaurian by M.K. Brett-Surman. == Description ==

Due to the fragmentary nature of Texasetes, little is known directly from the fossils and the uncertain phylogenetic position limits inferable traits. The preserved teeth are unique in that they have a large ridge leading up to the apex of the tooth's crown, with this feature known in only one other taxon from southern England. The cervical vertebrae of Texasetes are concave, a trait shared with Animantarx, a possibly autapomorphy for the two. Texasetes preserves a highly elongated coracoid and thick glenoid plate compared to its relative Animantarx. Due to the taxon being a Nodosaurid, the taxon was covered in large armored osteoderms with smaller ossicles in-between, as inferred by Panoplosaurus, and no tail club. ==Classification==

Coombs assigned the specimen to the family Nodosauridae, though lack of overlap prevents a confident answer and in Arbour et al., 2016's phylogenetic analysis however, Pawpawsaurus was found closer to Europelta and Texasetes closer to Edmontonia. Additionally, a juvenile ankylosaur skeleton from the Paw Paw Formation was found to be closest related to neither Pawpawsaurus or Texasetes, but Niobrarasaurus in the 2016 analysis. The 2018 phylogenetic analysis of Rivera-Sylva and colleagues is used below, limited to the relationships within Panoplosaurini. }} ==See also==
