Opabinia regalis is an extinct, stem
group marine arthropod found in the
Middle Cambrian Burgess Shale Lagerstätte (505
million years ago) of
British Columbia...

Graham Budd's
analyses of
Kerygmachela in 1993 and of
Opabinia in 1996
convinced him that
these animals were
similar to onychophorans...

other known unquestionable opabiniid, with the
other being Opabinia itself.
There are

Myoscolex and
Mieridduryn that could...

Certain Dinocaridid genera, such as
