Mtal, between Mazagan and Marrakech (Jurassic of Morocco)

Where: Morocco (32.5° N, 8.3° W: paleocoordinates 28.7° N, 4.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Jurassic (163.5 - 145.0 Ma)

• The age of the rock which yielded these specimens is somewhat uncertain, but Dr.

•Roger has written us that it is either Upper Jurassic or Lower Cretaceous. We have no information in regard to the associated fossils; but these two cephalopods, taken by themselves, can be said to indicate rather strongly that the containing strata are most probably Jurassic, for almost all of the congeneric forms known seem to come from that system. Furthermore, with few exceptions, they are from the Upper Jurassic. [Species found in Upper Callovian strata in Tunisia]

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks

• "Lentil of reef limestone in conglomerate"

Size class: macrofossils
