Cambrocaris baltica is an Upper Cambrian arthropod from Poland.
Description
[edit]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. The fossil seems to be only lightly sclerotised, with no distinct cutinized areas. It is unknown whether Cambrocaris had a cephalic shield due to the dorsal area being partially damaged, however it is improbable for it to have had a large shield, with either a smaller shield comparable to Martinssonia or a lack of the feature entirely being the most plausible possibilities. Cambrocaris also had a large hypostome, with a bilobed bulge reaching the mouth.
Ecology
[edit]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.[1]
Etymology
[edit]Cambrocaris is named as such due to its Cambrian origin, and the species name baltica derives from its location on the Hel Peninsula, in the Baltic Sea.[1]
