A peculiar median transitory cartilaginous precarotid plate is developed forming a floor to the hypophyseal fenestra in the posterior orbital region of the intermediate developmental embryos of Pterocles alchata. Only its anterior portion is homologized with the precarotid commissure of some birds. Its homology to the taenia intertrabecularis of some other birds and reptiles, is refuted
