Unsure about the authenticity of these.


Recommended Posts

I am fairly new to fossil collecting. I have been to a few fossil sites over the last 3 years but I didn't get into it seriously until recently when I started looking beyond the occasional dig to purchasing actual fossils.

I am wondering about these two fossils. The ammonite fossil I purchased a long time ago when I was a child and I have no reason to believe it is fake. All the same, I have found no fossils quite like it online to compare or a guide that would help me.

The second one, the fossil shark tooth I got at a show in oregon, I suspect is fake. The matrix looks to have bubbles in it and I've been told an arrangement of more than one tooth is rare. What I want to know is if the entire tooth is fake or just the matrix.

Thank you!

Welcome to the forum. Please send us a better lit first photo and a close up of the root in the second photo.

My goal is to leave no stone or fossil unturned.

I think they are real.

The shark tooth is a common Morrocan shark tooth. Otodus ?

The ammonite may be from Madagascar.

Sorry about the quality. I am going to try and take some better photos when my phone finishes charging.

Hi :fistbump: !Nice fossils :D !

Those fossils are both completely real, IMO.They probably came from Morocco (at least,I'm almost sure about the tooth provenance).

About the ID'S:

1st-I think it's not an ammonite (order Ammonitida), but some sort of goniatite (order Goniatitida), that lived during the Paleozoic Era (Ammos only inhabited mesozoic oceans) and whose suture lines were much more simple.However, other photos are required if you want to conclude it precisely.

Here it is a pic to illustrate my point of view.

2nd-Probably an otodus obliquus tooth (very common in Morocco, by the way).If you want to compare it with the ones I have on my gallery, click on this link:http://www.thefossilforum.com/index.php?/gallery/album/2417-worldwide-fossils/

There is no matrix with this tooth. The smaller "tooth" is a cusp, and is part of the whole tooth. One cusp is missing. the part that You are calling matrix is actually the root of the tooth.

Can not tell if there is any repair to the root from the picture provided.

My phone does not take the best quality photos but I hope these are better.

@ynot

Thank you for all the information! I'll be sure to use the correct terminology next time.

Edit

Another suspicion that the root is probably faked is I found the same material on the tooth itself. Its a little Bloch on the tooth but it could be just left over from the restoration work???

@Gugiuta

Really??? That would be super cool, to be honest! I do love paleozoic era sea creatures.

The root looks like it's had some restoration/repair -- but that's perfectly OK, and not what one would call 'faked'. It's quite common for fossils to need some repair or restoration, some more than others, especially if they're to be handled. Enjoy your fossils, they're definitely very nice.

@sagacious

Thank you! I'm glad the general consensus is that htye are real. I made a beginners mistake of buying a fake mosasaur jaw and I was worried I had bought other fakes as well.

The pics are much better!

However, even with these new pics, I can't tell you exactly what it is.

Now, I'm leaning towards nautiloid or goniatite.

Hope someone can clarify the situation.

Guguita

I would agree with Moroccan goniatite. These fossils are fairly common but are often mistaken for ammonites.

Cheers.

Hey Rhoyle. I agree with the others that your first pic is from Morroco, and don't feel bad about the tooth being repaired. It happens to the best of us. some folks are also really good at making fakes too. I use to sell one heck of a lot of those Otodus teeth way back when and I would buy them by the 'flat'. and many of those were also repaired.
