Hi, my first post on this forum and probably not the most exciting for regulars on here.
I found this fossilised vertebra while walking our dog on Mablethorpe beach, part of the Lincolnshire coastline. This is not a usual place to find fossils, however it's around 40km south of the Withernsea cliffs which release many fossils as they erode at a rapid rate.
This is my first ever proper fossil find, so to me is quite a big deal. My son who's a geologist reckons it may be from a shark. The only thing that makes me doubt this is the fact that there appears to be a groove where the spinal column may have run with two locations either side where something has snapped off. Perhaps it is from a large fish. The material is fossilised and definitely not bone or cartilage.
