Dinosaur biogeographic structure and Mesozoic continental fragmentation: a network-based approach [PDF]

, 2016
Aim: To reconstruct dinosaur macro-biogeographical patterns through the Mesozoic Era using a network-based approach. We test how continental fragmentation affected dinosaur macro-biogeographical structure and evolutionary rates.

A Velociraptorine tooth from Alabama and its Paleogeographic Implications [PDF]

Feathered Dinosaurs Reconsidered: New Insights from Baraminology and Ethnotaxonomy [PDF]

, 2018
Birds could not have evolved from land animal ancestors because Genesis clearly states that birds and land animals were created on separate days. As a result, young-earth creationists have consistently opposed the theory that birds evolved from dinosaurs.
