Linuparus eocenicus is a rare species of lobster found rarely at a few London Clay sites such as Isle of Sheppey. It is often found as fragments due to how thin the carapace is.
Linuparus, the spear lobsters, is a genus of medium-sized to large spiny lobsters in the family Palinuridae.
It contains four extant species found at depths of 30–500 m (100–1,640 ft) in the Indo-Pacific, and 32 fossil species, ranging from the Early Cretaceous to the Oligocene. L. trigonus is the only extant species also known from the fossil record.
