Waiting for answers about bad fossils

So I'm still in Quartzite. I'm waiting to hear back from Dr. Hans Larsson at McGill University about wether I'm correct in thinking that a couple of fossils being pushed by some Moroccan dealers are fakes. Actually, I think that they're composits; chimeras if you will. I think that the front end is of a mosasaur and that the back is of a crocodile. The dealers are selling them as crocodiles. Moroccans are sneaky when it comes to fossils. Alot of ammonites are really just carved bits of sandstone. A rediculous number of trilobites are either composits or total fakes. I'm waiting to hear back because I'd hate to be wrong about these fossils and miss out on a deal. The dealers are asking about $600 each, which for a mosasaur skull or a crocodile skull is cheap like borsht. Composits however have no place in museums and I'm only going after museum quality if I'm paying $600 a head.
