비고(Description): This plate offers an opportunity to own an example of a fine predatory Nematonotus fish. As they mature, Nematonotus develop a dramatic flag-like dorsal fin extension, hence the generic name longispinus. The dorsal here certainly lives up to that name, demonstrating this is an adult example. The genus became extinct during the Cretaceous. The detail in the caudal fin is remarkable; notice too the fine detail to the vertebral column. There are several partial shrimp of the genus Carpopenaeus present as well, with another on the reverse.
