izak_ Posted August 18, 2017 Share Posted August 18, 2017 I don't think its a fossil (or from any modern animal). Not sure what it is. @ynot 1 Link to comment Share on other sites More sharing options...
Sagebrush Steve Posted August 18, 2017 Share Posted August 18, 2017 Does a magnet stick to it? 1 Link to comment Share on other sites More sharing options...
Kingofthekats Posted August 18, 2017 Author Share Posted August 18, 2017 It looks like it broke in half No does not stick to a magnet Link to comment Share on other sites More sharing options...
Miocene_Mason Posted August 18, 2017 Share Posted August 18, 2017 Looks to me like a good old piece of chert, although the top part may be a burrow, let's see what others have to say. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Kingofthekats Posted August 18, 2017 Author Share Posted August 18, 2017 I thought it could be a tooth Link to comment Share on other sites More sharing options...
Ludwigia Posted August 18, 2017 Share Posted August 18, 2017 Definitely not a tooth. It's something geological. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Kingofthekats Posted August 18, 2017 Author Share Posted August 18, 2017 I guess there was a lot of things that were moved on to my property, I found out that my property used to be a trash yard Link to comment Share on other sites More sharing options...
Miocene_Mason Posted August 18, 2017 Share Posted August 18, 2017 Well that may be the origin of all the bones. Here's a link on the Ordovician check the life section to see possible creatures that you may find, your rocks seem to be of a river, estuarine, or marine environment. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

abyssunder Posted August 18, 2017 Share Posted August 18, 2017 Your specimen looks like ironstone , to me.

ynot Posted August 18, 2017 Share Posted August 18, 2017 Agree with a concretion, but will add that it looks stream tumbled. Darwin said: " Man sprang from monkeys."

Sagebrush Steve Posted August 19, 2017 Share Posted August 19, 2017 Sure looks like ironstone, but the specific gravity of 2.25 is about half of typical ironstone. Does it feel fairly hefty in your hand for its size? 1 Link to comment Share on other sites More sharing options...
Kingofthekats Posted August 19, 2017 Author Share Posted August 19, 2017 No it feels light Link to comment Share on other sites More sharing options...
Miocene_Mason Posted August 19, 2017 Share Posted August 19, 2017 Specific gravity matches chert roughly and chert is unmagnetic almost 100% of the time, so I'm sticking with chert. 1 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
ynot Posted August 19, 2017 Share Posted August 19, 2017 The round part is a solid concretion and the granular part is an iron stained sandstone. 1 Darwin said: " Man sprang from monkeys."

Sagebrush Steve Posted August 19, 2017 Share Posted August 19, 2017 I will throw out another idea, since his yard used to be a trash dump. It could be the fragmented remains of some sort of pottery. Kaolinite-based potters clay has a specific gravity within the range reported. 2 Link to comment Share on other sites More sharing options...
