Protopsyllidioids and their behaviour “frozen” in mid-Cretaceous Burmese amber

Fossilized inclusions trapped in amber often display great degrees of conservation for studies concerning their taxonomy, biodiversity and evolution, and in some cases, their ecology and behaviour. Knowledge on the biology of the extinct hemipteran superfamily Protopsyllidioidea is very scarce; the insight on the ecology and behaviour of this group is still lacking. Fossil protopsyllidioids conserved in amber can be of great value for acquiring...
