With good luck and perseverance, some beautiful fossils can be collected from the London Clay, which outcrops in the south east of England. The phosphatic remains of crustacea, fish and other, rarer vertebrates are well known, and information and images of them are easily accessed, particularly on the Internet site: www.sheppeyfossils.com. (See Fred Clouter’s article in Issue 9 of Deposits for a review of this website.) However, the formation’s hugely diverse floral assemblage is often overlooked, with little easily accessible information to be found on the web. Therefore, in this short article, I aim to introduce the most interesting of the London Clay’s plant fossils – its fossil seeds.
