I wonder if anyone has any ideas what they are. Could be just a farm animal but I wouldn't know where to start, the property is on the side of a small valley and a small river runs along at the bottom, the ground is very chalky too.
Many thanks in advance,
We were amazed to see your fossils as we have two the same and are very eager to find out what they are. We bought both fossils at a bric a brac sale at Fouquere which is a small village in the Charente, France a couple of weeks ago. Our daughter who is very interested in archaeology, palaeontology and anthropology and is studying at Yale university did some searching for us when we became baffled by our find and came up with your information then emailed it to us. We were wondering whether you have found out anything more. Did anyone suggest to you that it could possibly be a hippurite which is a Cretaceous bivalve? We have looked at the sites and it doesn't look like it to us. The hippurites don't have the root part which seems to indicate a tooth as both yours and our fossils have.
Hope to hear from you further.
I think these could be examples of 'cone in cone' structures - they are somewhat mysterious and their formation is still a matter of debate.
Thanks for trying to help us identify the two fossils we have. We looked at the Wiki entry on cone in cone structures. However we think the two individual examples we have do not appear to have been attached in sequence as in the examples shown. They also appear to have either muscle scars or some form of hinge attachment at the junction between the two cones. Take a look at these photos and see what you think.
It would appear to be very similar to this hippurite on ebay, same location as well
And this would explain the bowl like structures
Here is another example
John, thankyou so very much!, your research has made two boys very happy to know what they are. There next question was how old, I told them older than grannie!. The detail within the fossils on the ridges is amazing to look at, they are so large too, certainly something to admire for sure. May have to get the boys digging randomly on the next visit to there grandparents, if nothing else it will keep idle hands busy!! Once again many thanks for info it's been most appreciated :).
