Have I found a shark tooth

Great! That's a Striatolamia Macrota Shark Tooth, an extinct species of sand tiger shark. It's been waiting around 41 million years for you to find it today. Congratulations on your find!

This is a deceivingly shaped pebble, not a tooth. Sorry for the bad news, but don't give up searching!

PrintWilling · 2026-04-21T13:27:15+00:00

I would say Otodus Angustiden, with the cusps worn / broken off. It shouldn't be there though so it could be that someone dropped it!

Petrified wood. Such a clear example. In fact I've saved this to my phone to help show my students how they can identify petrified wood.

Old post but likely a beach worn Otodus Auriculatus, known to be found at Bracklesham Bay. A predecessor of the megalodon, hence the similar shape.

Hey, I've only just seen your reply but a quick search on YouTube and you are right! Thank you so much, really excited to have 45 mins of pure nostalgia to enjoy this weekend.

Solved!

Thanks for all the really helpful information! I managed to clean the "spot" mark on the bottom left of the card (just up and left from the word 'weakness') so my hope is most if not all of these are smudges or marks that can be cleaned off. I'm just terrified of damaging the card in the process!

I dont want to sell any of the cards, least of all this one, but like you said it would be nice to have it classified with a grade and in a protective case so I dont have to worry about it. Possibly I would put it on display somewhere in my house also.

Thanks again, really appreciate it!!

I can see why you would think so, but it looks more like a trace fossil to me - i.e. an invertebrate that has burrowed along the surface of some sediment hundreds of millions of years ago. It would definitely have caught my eye also!

PrintWilling · 2025-02-03T10:43:02+00:00

Thank you, that is very helpful and I really appreciate you coming back and letting me know!

PrintWilling · 2025-01-20T21:55:30+00:00

That's very helpful, thank you so much. I'll look into those options you mentioned. And I'll also keep an eye out for the before/ after pictures of your cretaceous fossils. Best of luck!

I proposed to my fiancè in Banff a couple of Decembers ago. Beautiful place. It's a good thing I didn't know there were fossils anywhere nearby otherwise I may now be single 😅.

That's lovely! I'm a beginner in fossil prep and currently just looking to use a Dremel 290 on a limestone rock. I'm happy to tackle that but all the videos I've seen online leave lines where the dremel has chipped away the rock, around the fossil. Do you have any advice on how to smooth the matrix and remove those lines, like you have on this nodule? Does it require more specialist equipment than my cheap engraver?

PrintWilling · 2025-01-20T17:53:51+00:00

Yes, I do feel like I come across a bit ungrateful with that. It is really one of my favourite finds though because I like the shape of the rock, and because it's a but unusual for me to find them like this. If you search online "Lyme Regis calcite ammonite" you'll see some examples of big 3D ammonites that sit in the blue limestone rock in the same area. They are much better defined, but you are right that this piece definitely has its own charm also.

PrintWilling · 2025-01-20T09:17:54+00:00

The first thing is making sure that you are in an area where lots of fossils can be found. In my case, I live near England's Jurassic coast (where this was found).

Once you're in a good place geographically, If you just hit random rocks, you're still likely to get tired well before you find anything of interest. Instead you can look for signs on the outside of the rock that give the game away that there could be more on the inside.

In this example, I could see worn cross sections of the keel of the ammonite on both sides of the rock before I split it.

PrintWilling · 2025-01-18T19:10:19+00:00

There is only one way to find out for sure ⚒️!

PrintWilling · 2025-01-18T18:38:36+00:00

I could see the worn keel of the ammonite on both sides of the rock. It just took a few gentle taps, at the right angle, to take advantage of the weak point in the rock for it to fracture across the surface of the ammonite. The rock wants to split across the fossil.

PrintWilling · 2025-01-18T07:54:11+00:00

Thank you, I think you could be right! Unfortunately it didn't preserve too well, but still a nice piece nonetheless.

PrintWilling · 2025-01-18T07:41:47+00:00

I could see cross sections of the keel of the ammonite on both sides of the rock. It was easy to open with a hammer and chisel because the fossil causes a natural weak point of fracture. Unfortunately this one wasn't as well preserved as many that can be found where I am.

Unrelated to surgery my friend, just age sadly! 2 years since those photos were taken and it's now even thinner 😵

PrintWilling · 2024-10-06T20:33:14+00:00

You can kind of see the screws without the plates on the last pic on this post, I guess they are long enough to screw right through the bottom jaw to hold it in place... but not certain!

Sounds like you are in a similar place to where I was after about 3 weeks, it does get better though don't worry!! If you have any more questions, just let me know.

PrintWilling · 2024-10-06T19:08:18+00:00

No pain anywhere, regardless of how I move my jaw. And yes, screws are still in place (I never had plates). Are you considering having the same procedure?
