Inktober 1. I brought out the coloured inks and went to town. Inspired by photographs of ammonite fossils, some of which show beautiful subtle colours in the shells. (This is obviously pretty over-the-top in terms of colouring)
Ammonites were sea creatures which existed 240 to 65 million years ago. They belong to a group of predators known as Cephalopods, whose current living members include the octopus, squid, cuttlefish and the nautilus.
Ammonites survived three catastrophic events before becoming extinct at the end of the Cretaceous period.
They probably lived in shallow pools, and lived roughly two years. They presumably stalked and hunted their prey -molluscs, fish and other Cephalopods, then rapidly extended their tentacles to grab them and devoured them!
