 Description:
This trilobite is a member of Order Redlichiida
that is named Bondonella szduyi. The Issafen Formation
where it occurs in Morocco is dated to be Early
Cambrian. It was originally described some 60 years ago
when it was placed in genus Neltneria,
which was revised in 1993, when it was placed in the new
genus Bondonella. There is a
second
known species Bondonella
typica.
Bondonella szduyi comes in two forms, one called the narrow form
and the other the wide form. It is unclear whether the two forms
differ due to compression and
or is, in fact, an entirely different species.
In either case, Bondonella is a rare trilobite.
