Are my fossiles genuine or fake?
buraqing34 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, im new in fossiles collecting, absolute new beginner. I wonder if my fossiles are genuine or fake, i was so proud of my collection but after i learned that there are many fake Moroccan trilobites on sale, i had suspicions. There are some holes in trilobite and some stuff on it, could be glued which is fine because its age matters to me most, it could be glued no problem. I put them under a plastic sheet but if you wish i can take them out to take better pictures. -
A year or so ago a friend of mine was moving to a new job, and he decided to downsize his collection and concentrate on his real interest, elasmobranchs (sharks/rays) and fish. As a result I inherited a number of fossils, including a Moroccan trilobite. It had a few cracks that had been crudely "repaired" with clay. Recently I decided to "restore" it, which means I removed the clay (toothbrush prep) and returned it to it's unaltered state. I initially thought it was one of the common Flexicalymene ouzregui but as I cleaned it up it looked a little bit different from that species, and also a bit familiar. I pulled up a paper (Destombes 1966) that @piranha posted here last year, and discovered that I actually had a Colpocoryphe grandis (Snajdr), a species I did not previously have in my collection. It is a decent size, 81 mm long by 41 mm wide across the free cheeks. Overall this species is similar to Flexicalymene ouzregui. The easiest to see character is the lack of pleural segments on the pygidium. The cephalon is also subtly different. Here is the figure from Destombes (1966) of Colpocoryphe grandis for comparison to my specimen:
