Repaired, Composite, or Fake Spinosaurus claw? How to spot the signs.
Genetic Algorithm posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good day and thank you for reading! I bought a 7-inch Spinosaurus claw in an auction and was hoping to get a second opinion on the condition and authenticity. I can send it back within a month for a full refund. I am also hoping for some pointers in knowing if is repaired or a composite. I have read many of the forums on here, but I have more questions. The length is 7 inches, but I do not have a ruler at the moment. This fossil is supposedly from the Kem Kem beds in Morocco. Any help is appreciated! Btw I do not have many fossils and plan to display this one to the public at my work if I keep it. Reasons why I do not think it is a composite or a carving: The texture and colors match on both ends of claw. They are also appropriate for fossils from Morocco. The shape and feel are good. Blood grooves follow the correct path. Reasons why I question if it is repaired or a composite: The darker brown areas do have a smoother texture and the grain is not visible in the very dark areas. How can you tell if this is substrate or cement/glue? If it is cement or glue, this piece could have been broken in half at some point, since the darker material has a concentration at the center and the tip. The blood grooves are not the exact same size on either side, though they are close. One side is wider. The darker areas do cause some "muddiness" but I cannot tell if it substrate. It is a bit lighter than I expected, but feels solid and has a similar feel and sound to other fossils when I tap it. The density feels similar to a Spinosaurus tooth, but feel less dense than a megalodon tooth. -
Some scientist think that impact events may have been responsible for more than one extinction event. Have any fossils ever been found that is preserving evidence that they may have died or were involved in an impact event.?
