Identification for Mosasaur and various sea fossils

[Kaiju Slayer333]

I had done a post about the tooth. So the info on the Mosasaur tooth is that it’s from Morocco. That’s all I know about it and if someone could figure out the specific species that’d be great. I also would like to know what the creature was for my other fossils.

The fossil on the very top under the dish, I don’t know what it belongs to as well as the ones on the bottom. Which could be pieces of bone. If anyone knows what those are and the Mosasaur’s species, I’d much appreciate it

Take a closer image of the bone pieces and say something about their provenance. Proper lighting, a central focus on the specimen, scale/measurement, and as much information as possible assists our members here in providing an identification.

 

It is a very good idea to read our pinned topics in the Fossil ID thread prior to posting a request, such as this one:

I think the mosasaur tooth is probably a composite. The crown may be real, but if you look at the upper section of the root, you'll see that there is a huge chunk of plaster that connects the crown and root. Plaster is notoriously used to fake a root or to connect two non-associated roots and crowns into a chimera when it comes to moroccan mosasaur teeth. I bet that if you scratch off the plaster you might find superglue inside. 

However, I can guess that the crown may be from a Prognathodon mosasaur, based on the robust build, color and striations, and lack of flat sides.

That makes sense because I look at other teeth and the actual teeth look extremely alike but the root not so much. 2 additional things, I really like Proganthodon so that’s pretty cool and thank you by the way. 2 I’ll take a look at the tooth and I’ll tell if I find anything.

Your mosasaur tooth photo is very good.  the second photo... well.... if you could take a good photo of each fossil, it would help us help you.  I also think it is a bit of a composite... real tooth, real plaster, and real bone, but not actual tooth root.  This is incredibly common with Moroccan mosasaur teeth.

I’m not sure, I’m pretty sure that small piece of “lime stone” is some type of coral

[Fossildude19]

Could be a horn coral. Would have to see the wide end. 

Your other piece looks like glass to me.

 

[Kaiju Slayer333]

I believe it’s amber. Especially because how bumpy it is. And it just has this weird feeling that isn’t like glass. And the horn coral has a bit of a round end on the wide end.

[M Harvey]

i am also thinking amber due to the internal discoloration.  and lack of a defined smooth surface glass would have.  Could the cone shaped object be a coprolite?

[Kaiju Slayer333]

That’d be interesting. But I think it’s a sea fossil so I doubt it.

[Tidgy's Dad]

Many sea-creatures leave coprolites behind. 

Coprolites of fish and sea-reptiles are fairly common in many places.

But we still need better pictures. 

The other piece still looks like chert to me, not amber.

I agree about the Mosasaur tooth. The tooth crown does look like Prognathodon sp.

But it's indeed a composite, the root is a random piece of bone that was filed down to fit the general shape of a tooth root. Together with a real tooth crown these were placed onto a real piece of matrix.

[Kaiju Slayer333]

Well as long as the tooth, the center focus of the fossil is real. I’m fine 

[caldigger]

Could the little piece in the last picture be shark coprolite? It seems to have that tell-tale spiral twist and shape.  Hey Lori!!!

[Kaiju Slayer333]

 

Actually, judging from other specimens, it could very well be that
