Hello All I've collected a sample of rock from the Warwickshire Jurassic that has a small 'clump' of fossils about 1.5 cm x 1cm on it. It was mucky in the quarry but when I cleaned it up I found that the clump mostly consists of tiny ammonites. They range from about 4mm to smaller than I can resolve with a hand lens. If all the tiny bumps are extremely tiny ammonites there might be hundreds contained within this small area. Has anyone come across this before? Should I try to find an interested expert to look at it? I wondered if it might be faeces from something that ate the ammonites or have I got some kind of ammonite nursery on my hands?
