Buccaspinea is an extinct genus of Cambrian hurdiid radiodont from the Marjum Formation, known from frontal appendages and a nearly complete albeit headless specimen with a preserved oral cone.

Buccaspinea means "thorn mouth", referring to the large hooked spines on its oral cone.

[1] Buccaspinea is roughly 10 centimetres long and has large, long-spined appendages seemingly used for capturing benthic prey, as they are not branched for sifting sediment or filter-feeding.

Buccaspinea appears to be closely related to Hurdia and Peytoia, sharing many characters with them, for example a lack of inner teeth, weak posterior tapering and many flap-bearing segments.

Unusually, it does not seem to have dorsal flaps, a trait unique to it and a few other hurdiids, such as Cambroraster.
