Etymology
The generic name, Harajicadectes, is derived from the geologic member the specimens were found in, the Harajica Sandstone Member, and the Greek 'dēktēs', which translates to 'biter'. The specific name, zhumini, honours Prof. Min Zhu of the Institute of Vertebrate Paleontology and Paleoanthropology, Beijing, China, for his numerous contributions to early vertebrate paleontology.[1]
Description
Choo et al. (2024) assigned a holotype and paratype to Harajicadectes, NTM P6410 and CPC 39948, respectively. The holotype consists of a partial skull and much of the body outline in dorsal view with squamation preserved. The paratype consists of a partial skull, the right post-temporal, and the right lower jaw.[1]
Classification
Choo et al. (2024) recovered Harajicadectes as a stem-tetrapod in their phylogenetic analyses. They reconstructed two trees collated from 336 most parsimonious trees. The first tree is a strict consensus tree, the numbers represent Bremer support values. The second tree is a 50% majority-rule consensus tree, the numbers are node support bootstrap values.[1] Their results are reproduced below:
