Collignoniceratidae is a family of Upper Cretaceous ammonites characterized by typically more or less evolute shells with compressed, oval, or square whorl sections; serrate or entire keels; and dense ribs with one to 5 tubercles.

Taxonomy

edit

This family, named by Wright and Wright in 1951, is divided into four subfamilies; Collignoniceratinae, Barroisiceratinae, Peroniceratinae, and Texanitinae. The family is included in the large ammonitid superfamily Acanthoceratoidea which lasted until the end of the Cretaceous.

The Collignoniceratidae are derived from the Acanthoceratidae, first appearing early in the Turonian (early U Cret) and lasting until the mid Campanian (late U Cret), a span of some 20 million years
