|Here is a very nice Kepplerites gowerianus from the British middle Jurassic.|
The Ammonite is preserved down to the first juvenile turn.
This fossil also shows that on some ammonite species the young (juvenile) specimens show a stronger ornamentation of the shell than adult ones of the same species.
