Guess the Grade Reveal! This gray wolf skull is an A Quality skull, defined as "as close to perfect as nature will allow." The unique feature you see above the left eye socket is not damage, but a healed wound from the animal's lifetime. An authentic, natural anomaly that adds to its story. Even A Quality skulls can show signs of minor pathology. After all, perfection in nature sometimes comes with a scar.

Just another day at the office with a freshly washed whale jaw. This bone had become somewhat brittle so extra care was taken during this cleaning. From here. this specimen will go through further washing, whitening and degreasing before it's ready for display.

Most of our surprise guests in the office are here to see Sir Indiana Bones but this big guy (who is wrapped all the way down that leg) was brought in to tour the facilities before being set back out in the field. Have any of our local friends seen any bigger rat snakes this year?

✅ Skull ID Challenge Reveal: Leschenault’s Rousette Fruit Bat
Unlike most bats, these fruit-lovers rely heavily on vision and echolocation produced with their tongue (not their larynx like most echolocators!).
Their skull reveals key traits:
🦇 A large braincase for enhanced sensory processing
🦷 Flat molars for crushing fruit
👁️🗨️ Wide orbital sockets to support their excellent low-light vision
Leschenault’s Rousettes are important pollinators and seed dispersers in Southeast Asia — helping maintain ecosystems with every flap of their wings.

Skulls Unlimited International, Inc. is committed to providing legally and ethically obtained natural bone osteological specimens as well as the finest replica specimens to the educational, medical and research communities. Through superior products, ever-expanding variety and outstanding customer service, Skulls Unlimited strives to serve our community as well as the World, in being the leading supplier of osteological specimens.
The evolution of Skulls Unlimited started when, at age seven, I found a dog skull in the woods near my home. When my father saw my interest, he encouraged me to find and collect other skulls, thus making it a life-long hobby. As I grew, so did my skull collection. After graduating high school, I collected and sold skulls in my spare time while working as an auto body technician. As sales grew, my wife Kim and I began to clean skulls in our kitchen. Starting with a one-page price list, in 1986, we turned this unusual hobby into a business.
Four years later, Skulls Unlimited evolved from this small home-based business into a successful retail & mail-order company. Then in 1992, fueled by local and worldwide enthusiasm, we became Skulls Unlimited International, Inc.
Currently, we've earned a reputation with some of the most prestigious museums & educational facilities in the world for having the best quality, most professional services, and the largest variety of natural bone specimens found all over the world.
Many of you have requested species that are not available in natural bone. In order to accommodate your needs, as well as our continuing efforts to protect the environment, you will find more than 500 replica skulls & skeletons of rare or endangered species throughout our website. All natural bone specimens are legally and ethically obtained. Suppliers World Wide send skulls that would otherwise be discarded or destroyed, as they are collected.
We do not condone and will not support poaching of animals, nor do we approve of destroying an animal solely for the purpose of gaining an osteological item. Our suppliers and their sources obtain osteological material from natural & predator deaths, road kills, food source by-products in exotic regions, legal hunting & trapping operations, and from attrition in zoological gardens. You can be assured of, and take comfort in knowing that your purchase conserve treasures and promote the ethical utilization of limited resources.
In 2010 the we opened SKELETONS: Museum of Osteology in Oklahoma City, OK to showcase specimens from my personal collection. In 2015, a second museum location was opened in Orlando, FL. These museums allow Skulls Unlimited to showcase hundreds of skull and skeletal specimens acquired over the years, but also provide an insight on the otherwise hidden workings of the animal kingdom. The goal of our museums is to serve as an educational experience, with the hopes that through education, an appreciation of the natural world will ultimately lead to conservation for the future.
With the continued growth of Skulls Unlimited and SKELETONS: Museum of Osteology, who knows what the future will hold?
