Animal Skull Identification Guide

Animal Skull Guide

Whether it be flying on a black flag symbolizing pirates or attached to a giant T-Rex skeleton staring down at us in a museum, the skull has forever fascinated us. We are all familiar with our own skull of course, but could you identify what animal a skull belongs to just by seeing it by itself.

The skull can be a valuable tool when it comes to identifying a species, understanding its anatomy and dietary habits, and helping us understand evolution. Although most natural history museums have displays of animal skulls, it can often prove difficult to find a quality guide that can help you identify specimens you may come across in the field.

We have put together a brief online guide of animal skulls from around the world which you will find below. We give our thanks to the many museums, nature centers, taxidermists, and teaching collections for allowing us to photograph the species found in this guide.

For a more complete animal skull identification guide, we highly recommend the following books.


Skulls: An Exploration of Alan Dudley’s Curious Collection

Skulls is a beautiful spellbinding exploration of more than 300 different animal skulls­—amphibians, birds, fish, mammals, and reptiles—written by New York Times bestselling author, Simon Winchester .

At the center of Skulls is a stunning, never-before-seen-in-any-capacity, visual array of the skulls of more than 300 animals that walk, swim, and fly. The skulls are from the collection of Alan Dudley, a British collector and owner of what is probably the largest and most complete private collection of skulls in the world. Every skull is beautifully photographed to show several angles and to give the reader the most intimate view possible. Each includes a short explanatory paragraph and a data box with information on the animal’s taxonomy, behavior, and diet.

Book Review:

This is an absolutely stunning book. I bought this book because I like to draw and paint animals and decided it is time to learn more about animal anatomy and the unseen structure of the skull as the foundation to build upon. This book will be a valuable resource to any artist looking to do the same. You will not be disappointed, the layout and detailed photography of this book are amazing.

Animal Skulls: A Guide to North American Species

Comprehensive guide to the animals of North America. Fully illustrated with drawings and photographs. User-friendly format makes comparing species easy.

Book Review:

Without a doubt, this is the best book on skulls ever written. If you live in North America, and want to know a *LOT* about the skulls of the animals on the continent (primarily mammals, but the book does also cover birds, reptiles, and amphibians in a more limited fashion), there is no better resource. I teach mammalogy at our local university, and waited a few years to buy my own copy of this book, since our campus library had one. Now that I have my own copy I don’t have to borrow it over and over again, and can go through it anytime I want. Definitely my go-to resource for all things pertaining to cranial osteology.
