Pseudopulicidae

Pseudopulicidae is an extinct family of stem-group fleas from the Middle Jurassic to Early Cretaceous of China.

Pseudopulicids are much larger than modern fleas, varying from 8 mm to over 2 cm in body length.

The body is flattened, with a non-reduced thorax, and covered in posterior-facing hairs (setae).

The mouthparts are siphonate, with a piercing-suctorial function, and are serrated and longer in females.

Proposed hosts have included primitive mammals, dinosaurs, and pterosaurs.
