Ray-finned fish are an incredibly diverse group of vertebrates – in fact there are over 32,000 living species which represents over 50% of all living vertebrate species!

Within the London Clay, Ray-finned Fish are represented by over 80 named species but there are many more unique specimens that are being found regularly in the London Clay so the number of species will grow significantly.  

Here we showcase all of the named species from the London Clay, dating from the Ypresian (Eocene) 50-54 million years ago. I will also showcase other unique specimens which I believe represent new species but are yet to be described.
