Cranial Osteology of the Hylid Frog, Smilisca baudini

This detailed study explores the internal skull structure of the Neotropical tree frog Smilisca baudini, filling a long‑standing gap in amphibian anatomy. Drawing on meticulously prepared transverse sections of an adult male specimen, the author maps each bone, cartilage, and connective tissue element in a clear, anterior‑to‑posterior sequence. The work combines precise microtome techniques with stained and cleared preparations, offering vivid illustrations that bring the hidden architecture of the frog’s head to life.

Beyond the descriptive catalog, the monograph highlights how subtle variations in cranial morphology can illuminate broader taxonomic relationships among hylid frogs. By linking internal skeletal features to previously noted external characters, the research provides a valuable reference for herpetologists and evolutionary biologists alike. Readers will appreciate the careful methodology, the transparent terminology, and the potential this foundation holds for future comparative studies across amphibian groups.
