Help needed with Asteracanthus tooth

By | News | No Comments

The Blisworth Limestone is variable both in thickness and in character. It is not oolitic and tends to weather grey such as the matrix you see below. The oyster Praeexogyra hebridica is abundant with some nice examples showing here.

When I found this particular tooth apart from the root missing it would appear to be complete.

Would anyone know what part of the Hybodonts dentition this tooth would be from.

Ketton Quarry report back : June the 2nd : 2018

Wonderful day at Ketton Quarry with members of the SDGS. This site has probably the best section of the Middle Jurassic strata in the East Midlands. Our trip took us through the quarry revealing rocks from the Upper Lias Clay to the Kellaways sands and clays. We were also privileged to visit the northern part of the pit to view some fantastic faulting.

As a group we mainly concentrated looking for fossils in the Upper and Middle Bathonian sections.

Here’s a few scenery and fossil photos of the day from some of our members. With more to follow 🙂

Various Asteracanthus teeth in situ and cleaned up.

Also we were allowed to hand hold some of the fossils that had been found around the quarry over the years. And that have been donated by various visitors. With this one below that had been donated by “Alan Dawn” himself. It has no provenance associated with it whatsoever. If anyone should have any information on this very intriguing fossil, then do let the society know.





Thank you for all those Involved at Ketton Quarry for making a great day out. And see you again soon.
