From the album: Middle eocene fossils from Qatar
Rare specimen of a cylindracanthus rostrum. It is from midra shale fm qatar and middle eocene aged. The exposed part is around 5 cm in length. I attempted to remove the tooth from the matrix but then it began to fall apart, so I will try to get b72 and soak the entire specimen before doing anything else with it. First ever recorded specimen from midra shale fm-

Hello dear forum users. I want to share a couple of findings and ask a couple of questions As I understand it, the image shows two fragments of Cylindracanthus rostra. Do I understand correctly that the frequency of longitudinal lines is not an indicator of species affiliation? Need to see a cross section? I found this information and understood it this way. Maybe you can help me understand this issue and recommend literature. I enclose links to the fact that in different parts of the rostrum there are different frequencies of protrusions. best regards, Anton Trans-Urals our finds on a red background https://zenodo.org/record/3660367 https://ammonit.ru/foto/62060.htm
