Common name Spiny Lobster
Fossil group Crustaceans
Order Decapoda
Family Palinuridae
Genus Linuparus
Taxonomic status Accepted
Geological age Ypresian

Summary

Linuparus scyllariformis was another spiny lobster of the London Clay. It would have been a heavily armoured seabed animal with long antennae used for sensing its surroundings and for defence, while the walking legs carried it across the bottom in search of food.

Like living spiny lobsters it was probably an opportunistic feeder on small invertebrates and carrion. The coexistence of two Linuparus species shows that spiny lobsters were a well-established part of the early Eocene marine community.

Quick Identification

Look for: a broad, strongly built Linuparus carapace with palinurid groove and ornament patterns; compare the complete carapace with L. eocenicus and do not create Thenops scyllariformis as a separate record.

Diagnostic Features

  • Robust palinurid carapace without enlarged clawed-lobster chelae.
  • Carapace relatively broad and strongly built.
  • Regional grooves provide a consistent cephalothoracic pattern.
  • Surface ornament and proportions differ from Linuparus eocenicus.
  • Historical name Thenops scyllariformis refers to this species and is not a separate taxon.

Fossil Details

Typical size
Centimetre-scale carapace and body; exact range is not securely established.
Fossil material
Carapace, Crustacean Appendage
Preservation
Broad carapace fragments may be distorted by compression. Fine ornament and the margins are particularly vulnerable to abrasion, reducing the characters available for separating the two London Clay Linuparus species.
