Belemnites were squid-shaped cephalopods. In the foreground, one has caught a small fish. Behind, another belemnite escapes from the jaws of an ichthyosaur, spewing ink as it swims away. Floating above is a tree trunk covered with crinoids. At lower left are slipper-like shells called gryphaea. The fish on the right are Dapediums. At the top right is an ammonite; on the seafloor are some ammonite and belemnite shells together with an ichthyosaur skeleton. Some of these may become fossilised.
