Placenticeras meeki is an ammonite species from the Late Cretaceous. These cephalopods were fast-moving nektonic carnivores. They mainly lived in the American Interior Basin ( Western Interior Seaway).
Shells of this species could reach a diameter of about 1 metre (3 ft 3 in). They are discoidal, involute and compressed. Whorls are stout and rounded to diameter of 3 millimeters. The surface of fossils is usually covered by opalized nacre ( ammolite).
The name honours Fielding Bradford Meek.
