He then investigated the rich deposit of fossil vertebrata at Pikermi and brought to light a remarkable mammalian fauna, Miocene in age, and intermediate in its forms between European, Asiatic and African types.

Taxonomists place lampreys and hagfish in the subphylum Vertebrata of the phylum Chordata, which also includes the invertebrate subphyla Tunicata ( sea-squirts ) and the fish-like Cephalochordata ( lancelets or Amphioxus ).

These include three major volumes : " On the Origin of Genera " ( 1867 ), " The Vertebrata of the Tertiary Formations of the West " ( 1884 ) and " Essays in Evolution ".

The unique morphological characteristics of lampreys, such as their cartilaginous skeleton, suggest they are the sister taxon ( see cladistics ) of all living jawed vertebrates ( gnathostomes ), and are usually considered the most basal group of the Vertebrata.

Hagfish are considered members of the subphylum Vertebrata, because they secondarily lost vertebrae; before this event was inferred from molecular and developmental data, the group Craniata was created by Linnaeus ( and is still sometimes used as a strictly morphological descriptor ) to reference hagfish plus vertebrates.

In June 1878 he was elected a Fellow of the Royal Society and in 1881 was awarded their Royal Medal " " For his numerous and important contributions to animal morphology; and more especially for his investigations respecting the origin of the urogenital organs and the cerebrospinal nerves of the Vertebrata; and for his work on the development of the Elasmobranch fishes .

In 1832, Meyer issued a work entitled " Palaeologica ", and in course of time he published a series of memoirs on various fossil organic remains : molluscs, crustaceans, fishes and higher vertebrata, including the Triassic predator " Teratosaurus ", the earliest bird " Archaeopteryx lithographica " ( 1861 ), the pterosaur " Rhamphorhynchus ", and the prosauropod dinosaur " Plateosaurus ".
