Ollie77777 Posted January 31, 2022 Share Posted January 31, 2022 Hi I am hoping for an ID of this specimen I found around chalk cliffs on the north Norfolk coast UK. There are several echinoids, belemnites etc but I’ve not seen anything quite like this. My first thought was an egg but I know they’re pretty rare so I’m not too convinced, especially without any notable markings. It does however have a brittle shell like coating so it has me stumped. It’s approx 11cm. im new to this group so if I’ve missed any details please let me know. Thanks Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 31, 2022 Share Posted January 31, 2022 I think this is a concretion. They often form in concentric layers. No typical egg shell texture, and that layer looks too thick to be eggshell, which is usually very thin and brittle. Also, quite unlikely if no other eggs have been found nearby. 1 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

abyssunder Posted January 31, 2022 Share Posted January 31, 2022 Hi, I think you have a fractured concretion. The external layer is too thick for egg shell and has not the proper texture/morphology for an egg shell, unfortunately. 1 2 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Ollie77777 Posted January 31, 2022 Author Share Posted January 31, 2022 Thank you all for such a fast response. I did wonder if it was a concretion but again, it didn’t look like anything I’d seen. That’s still interesting to know, even if I’m a little disappointed it isn’t a fossil :) Link to comment Share on other sites More sharing options...

Ludwigia Posted January 31, 2022 Share Posted January 31, 2022 Sure is an interesting conversation piece at any rate. It would be easy at first glance to mistake that for an Oviraptor egg.

Mark Kmiecik Posted February 1, 2022 Share Posted February 1, 2022 Many times concretions form around organic material. There may be a fossil inside that concretion. It may be worth carefully tapping it with a hammer until it splits open. You may get lucky. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

Plax Posted February 1, 2022 Share Posted February 1, 2022 maybe concretion or coating forming around a clay rip up clast? Not saying it is, just saying it may be. Link to comment Share on other sites More sharing options...
