aplomado Posted October 9, 2017 Share Posted October 9, 2017 My son found this in a creek LOADED with cretaceous fossils (shells, sea uchins, shark teeth). Is this a fossil or just a rock? Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 9, 2017 Share Posted October 9, 2017 Looks geologic to me, ... but wait for other opinions.

jpc Posted October 9, 2017 Share Posted October 9, 2017 I see nothing fossily, but then I am not holding it in hand. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted October 9, 2017 Share Posted October 9, 2017 Looks like iron concretion bit to me.

Carl Posted October 10, 2017 Share Posted October 10, 2017 I see no bone there. Looks like the ubiquitous look-alikes common down there. Link to comment Share on other sites More sharing options...
aplomado Posted October 10, 2017 Author Share Posted October 10, 2017 I was wondering if it might be a cast of plant stem? Link to comment Share on other sites More sharing options...

It appears to be bored by marine organisms but then concretions can be bored also. A bit oddly shaped for a rip up clast but it could be one that has gotten phosphatized in a lag deposit. The circular borings are trace fossils (if I'm seeing them accurately). Would like to see pics of the associated fossils. Link to comment Share on other sites More sharing options...
Carl Posted October 11, 2017 Share Posted October 11, 2017 If it is a plant it offers no fine detail to be certain of that. I suppose it's possible it's a burrow cast but out of context this would also be very hard to prove. Link to comment Share on other sites More sharing options...
fifbrindacier Posted October 11, 2017 Share Posted October 11, 2017 Hi, it looks like an ironish concretion with borings of sponge, or lichen maybe. It has, the kind of shape that hooks the curious eyes as the ones of a child. I'm a member of a club, and the only two childs who come fossil hunting with us (8 and 9 years old), are almost always the first to see something interesting : they are nearer from the floor, have a better view and are very curious about all funny shapes they see. So keep on looking for fossils and odd stones with your child, you'll both discover wonderful and amazing things and people. (Specially on that forum).

They found a lot of tiny shark teeth also. Link to comment Share on other sites More sharing options...

Uncle Siphuncle Posted October 11, 2017 Share Posted October 11, 2017 Any chance we are looking at Hardouinia bassleri? Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
