Today is International Women in Science Day and what better way to celebrate than to highlight some of the "Croc Docs" who track and research the alligators and even burmese pythons in the Everglades. The "Croc Docs" is a program through University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) carry out overnight conservation research projects that checks data on alligator populations as well as tracking invasive species.

For Pupo, a South Florida native, a career in science once felt unrealistic. Like many women in her family, she briefly considered medicine before rediscovering biology during her undergraduate years, inspired by female wildlife professors and peers who shared her passion.

“I can’t imagine a more fulfilling way to spend my time than helping to conserve the environment and the fauna that taught me so much growing up,” she said in the news release.

While skin bone plates are well studied in crocodylians (shown here in a gharial, in purple), their presence in lizards and snakes has long remained poorly understood. CT data provided by Jaimi Gray (2022, UF 33421) via MorphoSource.

With the horrible weather, it seems a great time to get into this study that looks at the how and why of osteoderms or the bony skin plate that many reptiles have and this awesome study gets deep into it!

The original belief was that animals with the bony plated scales all had a similar ancestor, but now with modern technology that has been disproven. So what was the origin?

We found that most lizards first evolved osteoderms during the Late Jurassic and Early Cretaceous, more than 100 million years ago. At that time, some of the most iconic dinosaurs roamed the Earth, including the towering Brachiosaurus, the fierce Allosaurus, and the plate-backed Stegosaurus.

The climate and ecosystems were changing rapidly, creating new challenges and opportunities. Armour may have helped lizards survive predators, cope with harsh environments, or move into new habitats.
