Thyreophoran Dinosaur Case Study

1.One anatomical feature in the vertebra is called the parapophysis which is part of transversal processes in the vertebrae. Transversal processes is a protuberance where that feature projects outward from the side of the vertebrae. Because the parapophysis is located on the dorsal side of the neural spine, one of its functions would be to help form a wide ribcage and provide sufficient space for a big gut.
Type of thyreophoran dinosaur: Stegosaurus
Case/ specimen number: uncatalogued
2. A homologous morphological structure that can examine is the bones that make up the hoof and legs of horses with the arms of humans. Both horses and humans exhibit the presence of similar bones such as the humerus, radius, ulna, phalanges etc. The phalanges is what mostly makes up the hoof of a horse and finger of humans have a different function in each specie. For example, while humans use their phalanges for grabbing objects, horses uses them for walking. This common bone structure is present in these two species because they both have a common ancestor/have shared ancestry. …show more content…
Analogous structures are structure similar between two or more species due to a similar environment and not because they have a common ancestor.
