I.—On a New Specimen of the Cretaceous Fish Portheus Molossus, Cope
Published online by Cambridge University Press: 01 May 2009
Extract
Several nearly complete skeletons of the primitive teleostean fish Portheus molossus are now known from the Chalk of Kansas; but none is better preserved than a remarkable trunk, nearly 12 feet in total length, lately obtained for the British Museum by Mr. Charles H. Sternberg. The specimen is shown, of about of the natural size, in the accompanying Plate XVIII, where it is seen mounted with the head of another fish of the same proportions. All the bones remain embedded in the matrix exactly as they were found, and there is no restoration beyond slight repairs.
