Oligocene crustaceans

Nephrops is a genus of lobsters comprising a single extant species, Nephrops norvegicus (the Norway lobster or Dublin Bay prawn), and several fossil species. It was erected by William Elford Leach in 1814, to accommodate N. norvegicus alone, which had previously been placed in genera such as Cancer, Astacus or Homarus. The genus name Nephrops comes from Ancient Greek νεφρός (nephrós), meaning "kidney", and ὄψ (óps), meaning "eye", and refers to the shape of the animal's compound eye.

Palaeocarpilius is an extinct genus of crabs belonging to the family Carpiliidae. The type species of this genus is Palaeocarpilius macrocheilus.
