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.
