Story summary

A study from Queen’s University Belfast suggests injuries on hadrosaur tail vertebrae may indicate mating behavior and help differentiate males from females.
Researchers analyzed 500 fossils from various locations to identify healed fractures likely caused by males mounting females.
Darren H. Tanke (Canadian paleontologist) proposed the hypothesis, which now gains support from new evidence.
Experts including Dr. Filippo Bertozzo caution that more data are needed to confirm findings.
