Discovery and naming
The Gamatavus
In 2022, Pretto et al. described Gamatavus antiquus as a new genus and species of silesaurid based on these remains. The generic name, "Gamatavus", combines a reference to the type locality (Picada do Gama site) with the Latin word "atavus", meaning "great-grandfather". The specific name, "antiquus", is derived from a Latin word meaning "ancient".[1]
Classification
Pretto et al. (2022) tested the phylogenetic relationships of Gamatavus in the datasets of Ezcurra et al. (2020) and Müller and Garcia (2020), both of which show alternate positions for silesaurids — the former as non-dinosaurian dinosauromorphs, and the latter as early ornithischian dinosaurs. Their results are shown in the cladograms below.[1]
