Macrophyseter Posted July 25, 2017 Share Posted July 25, 2017 those are mosasaur teeth! Unfourtunatly, that is a composite jaw, which means that the teeth are real but the jaw part is fake. For the exact species of mosasaur could take a bit more hard, but my guess is that its a Prognathodon because of its robust shape and the thin part at the back side which I usually diagnose as a signature for prog teeth. May be wrong on that thou. 3 If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM! Link to comment Share on other sites More sharing options...
Miocene_Mason Posted July 25, 2017 Share Posted July 25, 2017 I'd agree prognathadon, but am as inexperienced as a very inexperienced thing, someone who knows more and can confirm is @LordTrilobite who should eventually share his opinion here. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

LordTrilobite Posted July 25, 2017 Share Posted July 25, 2017 Teeth Mosasaur teeth. Fake jaw. Yes, the teeth do indeed look like Prognathodon sp. except the front most tooth. That tooth on the far right looks like it could be Prognathodon sp. or possibly Eremiasaurus heterodontus. Depending on where the tooth sits in the jaw, the shape can vary wildly. The teeth look like pretty nice specimens too. The jaw sadly, as has been already mentioned, is a fake. A composite of random pieces of real bone to be exact. Generally how fake mosasaur jaws are made by placing a few random pieces of bone from the same area as the teeth and use glue and sand to fill in the gaps. This will partially hide the fact that they are different unrelated bones and they take the rough shape of a jaw. So most of the material used is genuine. There's a chance the bone pieces come from a mosasaur, plesiosaur, croc or turtle. But those bone pieces use are generally in such a bad state that they wouldn't be identifiable anyway. And now they are used to assemble a composite jaw there's not a whole lot that can be learned from it besides how to spot a fake. 2 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

The green river in utah is drowned in fish fossils, but because of that, many places may have been claimed or protected, so trying to find some on your own might drop you into a legal flat. But I do know that there are plenty of programs in utah where you as a group dig for those types of fossils legally (i guess the hosts own that piece of river) 2 If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

The river that runs from Wyoming to southern Utah and is called Green river is not the same as the Green River formation that produces fish fossils. The Green River Formation is mostly located in southwest Wyoming. There are several locations that allow digging for a fee, but most of the formation is off limits to collecting. 1 Darwin said: " Man sprang from monkeys."

Thank you for clearing that up. I thought I remembered researching that for a thread where @Navajo asked for sites, the main one is closed in October. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

There is a town in southeast Utah called Green river. Okay, after some searching, I found out that the Green River Formation is composed of mainly 4 oilshades/basins. The biggest one, which is called the Green River Basin itself, is in south west wyoming. The Washake Basin also connects to the Green River Basin, which also leaks into Colorado. The second-largest, the Unita, is in northeast utah south of the green river basin, and the Piceance Basin is in Colorado. All basins contain plenty of Green River Fossils. So a huge chunk of the Green River Formation is in Utah, but again, I guess that the Wyoming-side basin is most plentful or its just that the Wymoing government has most tolerance over it. And you probably may be mistaken with the Green River Basin that I said above, which is all in Wyoming.

Most of the rest of it that is public property is held in leases by oil companies. If they caught You in the monument part they would probably charge You with a felony, otherwise just trespassing.
