 Description:
This plate displays a fine example of a member of the order Redlichiida
known as Bondonella szduyi. Coming from the Issafen Formation
deposits of Morocco, it is firmly placed in the Early Cambrian.
First described over 60 years ago as a member of the genus Neltneria,
a revision of the family Neltneriidae in 1993 led to the erection
of a second genus: Bondonella. This is the second species (see
my other listings for Bondonella
typica) known as Bondonella szduyi.This species comes in
two forms: a narrow form and a wide form. It is not clear whether
they are merely
compressed and extended examples of the same species or in fact
different species entirely. This is a fine, well-inflated example
of the wide form of this rarely-seen species. Some of the material
from Amouslek displays this black coloration, rather than the
brownish earth tones usually seen, making for a striking display
specimen
