Here is a good specimen of the fossil Slipper lobster of the species Acanthophoenicides peterpani. The fossil Slipper lobster itself is about 30 mm long.
The Decapod species Acanthophoenicides peterpani is interpreted as a pedomorphic representative within the Scyllaridae. The species name refers to the main character in James Matthew Barrie's children's stories. So Peter Pan, the boy who never grew up.
