19 T30. The Campanian Crucible: A synthesis of vertebrate paleobiogeography and ecosystem dynamics in Laramidia


Session Chairs:
Heather F. Smith, Brent Adrian, Andrew Farke

Laramidia’s Campanian deposits reveal vertebrate diversification, geographic isolation, and provincialism, and its fossil record informs paleoecology and biogeography. This session synthesizes research on evolution, endemism, WIS dynamics, and underexplored geochronology across this Late Cretaceous landscape.
