Asked a Question a While Back About Radiation in Fossils - Did an Experiment
GarethGP posted a topic in General Fossil Discussion
So let me preface this by saying I'm a hypochondriac. A hypochondriac who loves fossils. To my dismay a few months back I discovered that some fossils can be slightly hot and despite assurances from the lovely people here that my pterosaur (Alcione Elainus) radius from the phosphate beds in Morocco was almost certainly safe, I bought a cheap Geiger counter to do a completely unscientific experiment to test some of my fossils for radioactivity. These are all measured in microsieverts/hour: Normal background for where I live: Range after 1 hour: 0.10-0.17 Average: 0.11 -

Anyone planning to go to the Aurora Fossil Fest this month?
RandyB posted a topic in Fossil Hunting Trips
Wondering if anyone is planning to attend this years fossil festival in Aurora, NC Memorial weekend or if anyone who has attended previously has any recommendations/advice? I've spoken to the director and know the basics, just looking for any insight a first timer should be aware of. -

Carinodens belgicus. The corn-kernel toothed mosasaur. -
Identified as Carinodens belgicus based on occlusal aspect ratio (labiolingual/mesiodistal <2.2).

I had just bought this shark tooth online and was looking at some otodus shark tooth real or fake posts when i realized the root of this tooth is covered with sediments or maybe plaster?Can anyone help me take a look and see if its composited?

Hello Everyone, I had the honor of being invited by @markmg to a trip down into essentially ... a big hole in the ground. Woo Hoo !! A rather large gravel/sand pit that is being mined to 50-60ft ? We were not quite sure but hopefully at least as deep as the dredging that happens on the river. You know .. a play date ! .. haha Well, having just rained out my river trip on Friday I came prepared to slog through some mud. Let's just say it was lucky we didn't have a The Princess Bride (1987) moment because the water made the sand and mud a bit soft in some

I was offered this tooth it has serrations but it looks more mosasaur shaped. Any input is appreciated @LordTrilobite you have a decent amount of experience in dealing with mosasaur material correct?

Hi all, I have an ammonite specimen from Folkestone, UK that is locked in a phosphate nodule. Is there any way for it to be removed? Thanks, Jay

Can anyone identify this for me? I would think it was a crocodile scute, except Ive never seen that shape before.

From the album: Marine reptiles and mammals
A little collection of assorted mosasaur fossils from 2 different places that I got when I first started collecting. 2 different types of vertebrae, one is mosasaur, and the other is a questionable claim of mosasaur, a corprolite that was claimed to be that of a mosasaur, a tooth, & 7 rib fragments. 2 ribs have predation marks, as well as the large vertebra. The large vert has a round tooth indent on the very center. The 2nd rib down has tooth scratches along the surfaces, & 3rd rib down has a round tooth indent in the center, which is probably what caused a strip across the middle to -

From the album: Marine reptiles and mammals
2 unidentified mosasaur species' anterior end of premaxillary bones. One with teeth broken off just beyond the skull, and the other has 2 remaining teeth, with the rest broken off at the level of the skull. the larger fossil was found in the phosphate mines of Khouribga, Morocco. ive since lost the information for the smaller fossil, sadly. -
From the album: Marine reptiles and mammals
Unidentified Cretaceous crocodile species, suggested by multiple people, to appear to be a Dyrosaurus, came from the second phosphatic layer of a phosphate mine(what a shocker!)around the suburbs of Khouribga, Morocco. Original teeth, not replacements. Have gone through and cleaned up the base of some of the ones that had some sand around them. -

Hey Gang, So need your opinions on this one...We find alot of nodules down here and this one has a particularly well digested lumpy look to it, more so than most. Any chance you think this might actually be a coprolite? It does have a few clam borings and along the top wrinkle you can see some irregular parallel tubes that make me wonder. All thoughts are welcome. Thanks! Regards, Chris

I buyed this from a local dealer who, lucky for me i guess, not know what this was. He told me he found this in couche 2, which is Paleocene. I think this is a unique specimen because i never see this from the phosphate before.

Nearly finished this item, it did not survive the journey well (not packed by me) and was in numerous pieces. Turned out ok though IMO once stabilised and re-joined. Can you see the gastrolith? Nigel
