Richard A. Thulborn


Richard Anthony Thulborn was a British-born Australian paleontologist known for his pioneering research on dinosaur tracks and the palaeobiology of prehistoric vertebrates. He is recognized as one of the most productive paleontologists of his time and a leading expert in vertebrate ichnology.

Career

In 1976, Thulborn joined Dr Mary Wade and a team of volunteers to excavate the Lark Quarry dinosaur tracksite, located near Winton, Queensland. Their work uncovered what remains the world’s only known evidence of a dinosaur stampede, published in 1984, which captivated scientists and the public alike. He later critically reassessed these findings in Lark Quarry Revisited, demonstrating rigorous methods in ichnological interpretation. His work helped secure the site’s inclusion on the Australian National Heritage List in 2004, ensuring its preservation for research and public education.
In 1982, Thulborn debunked the purported plesiosaur embryos discovered by Harry Govier Seeley. Thulborn concluded that Seeley's supposed embryos were actually nodules of mudstone and shale derived from sediments that once filled in a crustacean burrow system and were not even animal body fossils.
Thulborn’s research also included dinosaur locomotion, thermoregulation, tooth wear, jaw action, reproduction, and palaeobiology across diverse taxa. He investigated the evolutionary relationships of birds and theropods, including studies on Archaeopteryx, digit homology, and flight mechanics.
Thulborn also made important contributions to understanding Australia’s prehistoric vertebrate diversity, including mammal-like reptiles, dicynodonts, Triassic vertebrate faunas, plesiosaurs, and coprolites. His critical approach and publications influenced both Australian and international palaeontology.

Honours

Thulborn was instrumental in securing recognition for Australia’s fossil heritage. He was widely respected for his scholarship and mentorship.
