Description: | Specimen of a fossil echinoid (sea urchin), Micraster sp., collected from the Chalk Formation (?) of Late Cretaceous age.
Micraster is a heart-shaped sea urchin. This one is white, because it is preserved in chalk, a very pure form of limestone. Fossils like this one have been called Fairy loaves, because it was thought that if a family kept some of these fossils in the house, they would not go short of bread.
It is from the Cretaceous period (144 - 65 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Echinodermata Invertebrata Echinoidea | Temporal: | Cretaceous period (144 - 65 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
