Skull Index Community Discord Server
Come join the official Skull Index Community server! We have an active and welcoming 18+ community of hobbyists, industry professionals, and academics. The server has several channels for specimen showcasing, advice or identification, and professional development. We also host monthly giveaways and plan to host even more community events in 2025. If you'd like to get involved with the project this is one of the best ways to connect with our staff!

What is the Skull Index?
The Skull Index is an entirely volunteer-run non-profit collaborative educational project. We are working with private collectors, educational institutions, and museums to create a public free to use osteological reference website.
The project was developed in 2023 between @birbbones, @dread-doughnuts, and another friend. We recognized that a gap exists between professional organizations and private specimen collectors, which we hope to bridge with our project. We also recognize that there is a lack of publicly available resources for hobbyist collectors and especially in the age of AI we feel it's important to create one.
We are always accepting submissions of new specimens for the website. If you have a specimen you'd like to submit more information can be found on our Get Involved page. The best way to get in touch with our team is either via email ([email protected]) or by joining our Community Discord Server, though we can also be contacted through messages and asks on this blog!
New submissions will be posted to this blog as we upload them to the website, however, we also have a queue running of previously submitted specimens that will be posted once a day.
We hope to see the project grow even more in 2025!
The Skull Index now has its own Tumblr account! If you want to keep up with the project be sure to give it a follow!

The animals at herp society today got a grim reminder of their own mortality.
and then... well, then there's Kyle.
It’s so fascinating to me that we’ve only been breeding Komodo dragons in captivity for thirty years. In that time, our understanding of them has actually really revolutionized the way we understand the social lives and behaviors of lizards in general, and it’s mostly thanks to this lady right here, who was born 30 years ago on September 13, 1992.
Kraken was the first Komodo to be bred in captivity. She hatched out at GMU, but was raised at the National Zoo. Her parents were wild-caught dragons- there’s still WC dragons in the AZA today- and this one specific individual probably did more to revolutionize lizard care in professional settings than any other individual lizard throughout zoo history.
Until Kraken, social enrichment wasn’t a thing people thought about. It wasn’t something anybody felt was necessary for lizards, because they were just… lizards. Sure, some keepers would play with their favorites, but it wasn’t until the National Zoo started documenting what she was doing that anybody realized how much Komodo dragons like to play with us too.
Kraken’s not in that video, but she’s the one who inspired all of the social studies that have been done on captive Komodo dragons. When she was at the National Zoo, her keepers started getting curious when, for no apparent reason, she kept gingerly stealing things from peoples’ pockets and tugging on their shoelaces. So they started giving her stuff- Frisbees, blankets, soda cans, anything she showed an interest in.
She played with them, just like a mammal might. The way play behavior is described in psychology is a given activity that’s voluntary, repeated, and conducted under “relatively benign” circumstances. Keeper staff found that her conduct during the study met all of these criteria. “Kraken,” they wrote, had clearly demonstrated “play-like behavior with objects and even with humans (tug-of-war).” Moreover, she “could discriminate between prey and nonprey” while showing “varying responses” with different items (rubber rings, shoes, etc.). (There’s an excellent book on Komodo dragons that has an entire chapter devoted to her.)
Kraken died several years ago, but her legacy continues today. There’s several of her descendants still in the AZA, and the intelligence and social needs she demonstrated led to the improvement of life for these guys- and other lizards. The Komodo dragon program has been an eye opener, not just for reptile conservation, but for understanding reptile intelligence and how this incredible clade of animals functions.
Happy birthday to the lizard who changed it all.
