Ammonites belong to the class of animals called mollusks. More specifically they are cephalopods. and first appeared in the lower Devonian Period.
Cephalopods were an abundant and diverse group during the Paleozoic Era. This specimen is just over 12cm in length, a little under the average of 13.4cm.
There are several localities in the archipelago of Haida Gwaii where Brewericeras can be found (six that I know of and likely plenty more!)
The islands of Haida Gwaii are at the western edge of the continental shelf and form part of Wrangellia, an exotic terrane of former island arcs, which also includes Vancouver Island, parts of western mainland British Columbia and southern Alaska.
This specimen was found on a trip a few years back done with the Vancouver Paleontological Society and a few of the members of some of the Island paleo groups. The preservation is quite remarkable!
Brewericeras are also found in Albian deposits in Svedenborgfjellet, Ulladalen, Norway (Cretaceous of Svalbard and Jan Mayen - så fin!) (77.7° N, 15.2° E: paleocoordinates 66.6° N, 13.6° E) and Matanuska-Susitna County, Alaska, 62.0° N, 147.7° W: paleocoordinates 57.3° N, 85.6° W (112.6 to 109.0 Ma.)
