Holotypes

E-mail Print PDF

The Alf Museum is home to the holotype specimens for 18 different species. The collection’s historical strengths have been in fossil footprints – thus, we currently hold 13 ichnotypes, from birds, camels, bear-dogs, and even a spider. More recent work has emphasized bony elements, with several mammalian holotypes as well as a dinosaur. Although published holotype specimens are not normally loaned, they are available for study. See the Collections Access page for more.

The links below lead to information on each type specimen, including photographs, bibliographies, and proposed synonymies. Only holotypes and lectotypes, but not paratypes, are listed here.
