Dollocaris is an extinct genus of thylacocephalan that lived during the Jurassic period.

Fossils have been found in France, specifically the La Voulte-sur-Rhône lagerstätte.

It is known for its massive compound eyes, giving Dollocaris a rather characteristic appearance.

[1] Adult specimens of Dollocaris measured over 30 cm (12 in) in length.

[2] It sported a row of small appendages to assist in swimming, as well as three pairs of clawed segmented legs,[3] but it was probably a poor swimmer, instead depending on ambush to hunt prey.
