(Siveter et al, 2015)

The 425-million-year-old Silurian fossil holotype specimen was found still attached to its fossilised host, a specimen of the ostracod Nymphatelina gravida, at an undisclosed location in England.[3] It is now in Oxford University Museum of Natural History. It was first described in the journal Current Biology in 2015.[1]

Etymology

edit

The generic name is a New Latin compound word combining "invasor" and "avitus," and roughly translates as "ancient intruder." The specific name refers to piracy; both names referring directly to the organism's obvious parasitic lifestyle.[1]
