PREVIOUSLY UNFIGURED TYPE SPECIMENS OF FOSSIL FISH, REPTILES, AND MAMMALS IN THE ACADEMY OF NATURAL-SCIENCES OF PHILADELPHIA

The Academy of Natural Sciences of Philadelphia holds the type specime ns of 400 species-level taxa of fossil vertebrates. Among them are 56 taxa whose types have never been figured, or have been incompletely fi gured. There are also plaster casts of two species, the original types of which (not owned by the Academy) were never figured and have been lost. This paper provides photographic illustrations of the unfigured types and a few previously figured ones for which there are new data t o convey to the scientific community.
