Title

TF0151

Bivalve (manmade external mould)

Description

Taxonomy

Phylum: Mollusca
Class: Bivalvia

Distinctive Features

Ribs

Preservation

Manmade external mould

Advanced notes

Although this particular specimen is a manmade mould, internal and external moulds are common ways in which bivalves are preserved.

Because they commonly disarticulate after death, external and internal moulds of one valve are also common, with the impression of the shell outlasting the shell itself, which is often dissolved.

Distinctive Features

Coiled shell (planispiral)

Advanced notes

This specimen resembles an ammonoid, in that it has a planispirally coiled shell. However note that there are no septa and the shell exists as one large chamber, allowing us to identify it confidently as a gastropod.
