Sereenity Posted May 24, 2023 Share Posted May 24, 2023 (edited) Goodmorning! A few days ago I went for a rockhounding session nearby, in Numansdorp in the Netherlands. They have a massive pile of rocks - for covering the road (so construction material). I have found lots of pieces of agates here. Probably it's mined somewhere like Steenwijk, but don't precicely know where they harvest these rocks. Besides the gorgeous agates I found in this pile, I also found something I have no clue about.. First I thought it was something like a squid, so extremely old.. but.. I looked around the internet - so now I am guessing it is some sort of tooth? Can somebody help me out with ID'ing this piece? And is it possible to have some sort of clue on the age of this? (not specific, but is it a day old or a year - like that :)). The measurments are in CM. Thank you very much in advance!

jikohr Posted May 24, 2023 Share Posted May 24, 2023 Hi, welcome to the fossil forum! Yeah that looks like a piece of a mammal tooth, most likely either horse or bovid, but maybe camel as well. I'm not the best with differentiating those, so we'll see what the experts say. Link to comment Share on other sites More sharing options...
rocket Posted May 24, 2023 Share Posted May 24, 2023 Yep, thats right, mammal tooth I would think it is a part of a horse-tooth 1 Link to comment Share on other sites More sharing options...

The Netherlands aren´t particularly famous for agates. mindat yields two pics: Agate - Photo Gallery (mindat.org) And one site: De Groot quarry, Landgraaf Municipality, Limburg, Netherlands (mindat.org) Maybe this is of some help finding out the provenance of the rubble pile! And would you like to share a pic or two of your agates? Thank you! Franz Bernhard Edited May 24, 2023 by FranzBernhard 1 Link to comment Share on other sites More sharing options...

Sereenity Posted May 25, 2023 Author Share Posted May 25, 2023 Hi all! Thank you so much for all the kind replies! So a horse tooth, cool to know As for the requests for the agates - ofcourse I can share some! For the reply on Flintstones - maybe you are correct, but I am quite sure they are agates..:) Also, I have found some baby agates in France last year - I have some images of that as well! 3 1 Link to comment Share on other sites More sharing options...
FranzBernhard Posted May 25, 2023 Share Posted May 25, 2023 Thanks for sharing your agates! Sure they look like proper agates. You said, you found them in gravel. So they could come from the area of Idar-Oberstein or the like? Franz Bernhard 1 Link to comment Share on other sites More sharing options...

You said, you found them in gravel. So they could come from the area of Idar-Oberstein or the like? Franz Bernhard Yes, indeed. The neighbors had to reinforce their driveway to the harbor - so they had a giant pile of stones lying around.. I tried to find out where such material comes from but - I quite suck at investigating it seems, haha. At the quarry in Winterswijk it's mostly Sandstone and calciet I read. Don't know if some Agate forms there as well..? I am quite a newbie in Agate finding - so spotting locations is still some trouble haha. In the summer we will head towards the French Alpes - hopefully I can satisfy the hunger for rockhounding there Link to comment Share on other sites More sharing options...

Did the pile consist of roundish or of angular stones? It seems, the material comes from fluvial gravel, could have been transport in a stream (Rhein?) for hundreds of kilometers.

It seems, the material comes from fluvial gravel, could have been transport in a stream (Rhein?) for hundreds of kilometers. Franz Bernhard Yes, they are absolutely water-worn indeed. Some of them still have some 'angles' like the first images but rounded of for sure. I am planning to go to the south east of Holland in a while - to search the Rhein nearby Germany.. Gonna start on location spotting for sure now haha! edit: Oh, sorry thats not the Rhein but the Waal... oops Edited May 25, 2023 by Sereenity 1 Link to comment Share on other sites More sharing options...
grandpa Posted May 25, 2023 Share Posted May 25, 2023 Thanks for sharing the agates; they are beautiful. The one on the top row, far right reminds me a lot of a Fairburn agate from South Dakota - lovely! Link to comment Share on other sites More sharing options...
jpc Posted May 25, 2023 Share Posted May 25, 2023 before you label the tooth as horse, look into premolars of a deer. Link to comment Share on other sites More sharing options...
