Skeletal completeness of the non‐avian theropod dinosaur fossil record
Palaeontology, Volume 62, Issue 6, Page 951-981, November 2019., 2019 Abstract Non‐avian theropods were a highly successful clade of bipedal, predominantly carnivorous, dinosaurs. Their diversity and macroevolutionary patterns have been the subject of many studies. Changes in fossil specimen completeness through time and space can bias our understanding of macroevolution.
