Howdy all. I'm one of those that value correct id's when it comes to fossils, so I thought that I'd post some common misidentifications often seen in anything from gift shops to proffessional collections. If you know any other misidentifications you are welcome to post them here First up are the "Orthoceras" slabs coming out of Morocco (all these misidentifications are of moroccan fossils). Orthoceras currently only contains 1 species, which is only known from my general area (Northern Europe), based on my research, the species originally called "Orthoceras fluminese" is the correct ID for the moroccan orthocones, and this species is today known as "Orthocycloceras fluminese". Second, another paleozoic invertebrate, the Moroccan calymenids are very common and are often labelled as "Calymene" or "Diacalymene", but neither genus exist in Morocco. The correct species for these trilobites is "Flexicalymene ouzregui". Third, we have the Moroccan Globidens teeth, these are often sold as "Globidens aegypticus", a species that according to both Wikipedia and the Paleobiology Database doesn't exist. The name you're looking for is "Globidens phosphaticus". Lastly, we have another mosasaur. "Mosasaurus anceps" or "Prognathodon anceps" teeth are quite common on the market, but they do in fact belong to "Liodon anceps", sometimes teeth labelled as "Prognathodon sp." Will belong to Liodon as well. I hope this helped

Yes, I am talking about the large otodontid also known as the false Mako, Parotodus benedeni, or is it benedenii? I’ve seen it both ways and I’m confused. I’ve always used single “I” but I don’t have any reason for this.
