Petalograptus minor (10)

This particular graptolite does not have the distinctive 'hack saw blade' morphology. This is a small fossil looking like a leaf or petal (hence the name). Each individual zooid lived in the chambers preserved only as the curved striated divisions.

Petalograptus minor lived in the Llandovery Series of the Silurian, this one is from the English Lake District.
