Tonight I am joined by Dr. David Blackburn. David has spent the majority of his career studying African Frog species, as well as frog evolution and morphology.  We begin with a discussion on frog evolution, extinct frogs, and the frogs in fossil record; and we continue on to discuss several African species including the goliath frog and a very rare species of Xenopus. We also discuss some of the new technology that scientists are using to study and recreate rare and extinct amphibian species.To support the show by becoming a Patron on Patreon, for AmphibiCast Merch, and for listener discounts on In Situ Ecosystems vivariums visit: https://linktr.ee/AmphibiCast To learn more about the topics discussed in tonight's show check out these links.Data repository for sharing CT-scans: https://www.morphosource.org/ 3D models for education and outreach: https://sketchfab.com/ufherps Lab website: https://www.floridamuseum.ufl.edu/blackburn-lab/ AmphibiaWeb account for Conraua goliath: https://amphibiaweb.org/cgi/amphib_query?where-genus=Conraua&where-species=goliath AmphibiaWeb account for Trichobatrachus robustus: https://amphibiaweb.org/cgi/amphib_query?where-genus=Trichobatrachus&where-species=robustus AmphibiaWeb account for Xenopus longipes: https://amphibiaweb.org/cgi/amphib_query?where-genus=Xenopus&where-species=longipes
