Description: | Specimen of a fossil ammonite, Hamites sp., collected from unspecified rocks of Early (?) Cretaceous age.
This unusual ammonite shell has two straight sections joined by a U-bend and is covered with widely spaced simple ribs. The animal itself (which looked like a small octopus) lived in the wider end of the shell. The reason for this unusual shape is unclear but it may be an adaptation for living on the sea floor (ammonites are usually free-swimming). Hamites lived all over the world in the Cretaceous period before it became extinct towards the end of the period, along with animal like the dinosaurs.
It is from the Cretaceous period (144 - 65 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Cephalopoda Classification: Animalia Invertebrata Mollusca | Temporal: | Cretaceous period (144 - 65 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
