Ep. 46 – Paleobiologist Thomas Halliday on the Animals of Ancient Worlds
The fossil record acts as both a memorial to life’s spectacular possibilities and as a warning to humanity about how fast dominance can become forgotten history, according to our guest, Scottish paleobiologist Dr. Thomas Halliday.
