Extract

Representatives of the ammonoid family Pronoritidae are ancestral medlicottioideans (Order Prolecanitida) characterized by moderately evolute conch and relatively simple sutures. They comprise the ancestral Pronoritinae, characterized by an undivided dorsal lobe, and the descendant Neopronoritinae with bidentate dorsal lobe. The new genus Paedopronorites is interpreted as the terminal neopronoritin paedomorph. It conforms to the pattern displayed by many late Paleozoic taxa (Glenister and Furnish, 1988a, 1988b), being the geologically youngest representative in the lineage, and characterized by small size, sutural simplification, and low abundance.
