... Lethiscus stocki . The fossil is found to have approximately 30 closely spaced teeth on its maxilla and dentary, a short vomer, a palatine running nearly the entire length of the maxilla that is toothed at least posteriorly, and a choana that is located at the premaxilla–maxilla suture. It has a lower jaw...
