Middle Triassic
Guizhou Province, China
ITEM# INVERT-China-0004
This is a museum-quality example of the ammonite Pleuronodoceras sp. from the Triassic of Guizhou, China. Pleuronodoceras sp. is a member of the Order Ceratitida, Family Pleuronodoceratidae.
This is an excellently-preserved example of an ammonite with a ceratititic suture pattern. The Ceratitida were widespread in the Triassic, and went extinct during the Permian. There were approximately 400 genera, the majority of which existed during the Triassic. Therefore, the order is important in the stratigraphy of Triassic deposits.
This order forms the majority of the Triassic ammonoids, with their suture line being ceratitic to ammonitic. In primitive forms the lobes are finely frilled, looking like the edge of a saw.
The specimen measures 1 1/8 inches long by 1 1/4 inches wide. The framed portion of this specimen is approximately 3 1/2 inches long by 3 1/2 inches wide.
