Anthracomartus is an extinct genus of Carboniferous-aged trigonotarbid arachnids.

A fossil of the species Anthracomartus hindi (synonym: Cryptomartus hindi) was found to be 23 millimetres (0.91 in) long and 14 millimetres (0.55 in) wide.

[2] Scientists at Imperial College London created a detailed 3D computer model of A. hindi from fossils.

[3][2] 3D imaging revealed A. hindi has a flat body and large front limbs, indicating ambush hunting techniques similar to that of modern crab spiders due to the similarities in their anatomical features.
