Holly Woodward Ballard is an American paleontologist and paleohistologist.

Biography

[edit]

Ballard is a paleohistologist known for her research in the field of paleontology, particularly in the study of fossil bone tissue microstructures to understand the growth and development of extinct animals.[1][2]

Research

[edit]

Ballard's research assesses ontogenetic growth and intra-specific variation in extinct tetrapods primarily through large-sample long-bone paleohistology, with a focus on non-avian dinosaurs. She also examines the intra-skeletal ontogenetic histology of extant tetrapods to improve understanding of bone tissue microstructures for use as a foundation in paleohistological interpretations.[3][4][5]

Publications

[edit]

Ballard's notable publications include:

  • Growing up Tyrannosaurus rex: Osteohistology refutes the pygmy “Nanotyrannus” and supports ontogenetic niche partitioning in juvenile Tyrannosaurus.[3]
  • Ruling Reptiles: Crocodylian Biology and Archosaur Paleobiology.[6]
  • The earliest Pleistocene record of a large-bodied hominin from the Levant supports two out-of-Africa dispersal events.[7]
  • Archosauromorpha: Avemetatarsalia – Dinosaurs and Their Relatives.[8]
