Cambrocaris

Cambrocaris is an extinct genus of Upper Cambrian arthropods from Poland.

Cambrocaris is an arthropod roughly 2 mm (0.079 in) long, known from a single, partial specimen with Orsten-type preservation.

The preserved section is 800 micrometers long and bears eight pairs of appendages with the anterior three being complete and further back only being partially preserved, [1] the first antennae being the longest appendages.

Cambrocaris also had a large hypostome, with a bilobed bulge reaching the mouth.

Cambrocaris, while possibly being benthic due to being preserved in sediment, nevertheless shows adaptations for swimming, and the presence of a mouth and lack of intricate bristles show that it presumably caught prey and swallowed it whole.
