Hello everyone. I am after the ID of these solitary corals. Location: Eastern Bulgaria, Rhodope Mts, south of Kardzhali Age: Oligocene, did not manage to pinpoint the exact location on the geological map, due to poor quality map. As per a local expert, the horn-shaped coral is a Placosmiliopsis bilobatus and the age is Oligocene. The species is supposed to have polymorphy; some are roundish, while others form slightly the number 8. I found a topic on a Spanish forum but I fail to understand the key elements determining the species. Through the help of Google translate, I understood that I have to create cross sections (vertically? horizontally? I made both) but I do not understand what I should observe. (Spanish text in the end of this post) Additionally, as per minedat, the P. bilobatus is supposed to have gone extinct up to Priabonian. This is the reason I started searching since one fact is against the other. The horn-shaped coral is approx an inch in diameter and 1.25" height. The discoid coral has a diameter of 1.75" and 0.25" thick. Both were cleaned with toothbrush and KOH. @fifbrindacier said that @oyo and @HansTheLoser might be able to help on this topic. I would appreciate your opinion. Thank you! "Placosmiliopsis: columnella laminar profunda / Pattalophyllia: columnilla trabecular. Solo hay que cortarle a un cucurucho su rabito y pulirlo un poco (con una muela de afilar cuesta poco), para ver si tiene una columnilla en lámina continua o una columnilla también lineal pero por una amalgama de trabéculas.... como en las últimas fotos de los links que ha puesto Elotro... ....para mi que es Pattalophyllia." This what it is supposed to be Placosmiliopsis bilobatus. There are some noumoulites or other foraminifera on top of it.
