Apankura

Apankura is an extinct genus of Cambrian euthycarcinoids from the Santa Rosita Formation of Argentina.

[2] Apankura is roughly 4 centimetres (1.6 in) long, and has large mandibles, a trait previously unknown from euthycarcinoids.

The antennae are uniramous like other euthycarcinoids, with a possible buccal complex present behind the mandibles.

The pre-abdominal limbs match other euthycarcinoids, although they taper distally and lack setae.

The post-abdomen is incomplete but composed of at least six segments, all lacking limbs, with the gut preserved as a dark line in the centre.
