We can’t know for sure if a dinosaur could be infected with COVID-19, but studies of coronavirus genomes indicate that they originated after the dinosaurs went extinct. There is evidence that dinosaurs were affected by other diseases, however.
Palaeontologists have identified many ‘palaeopathologies’ on dinosaur bones, which indicate various maladies including bone cancer, gout, a bone infection called osteomyelitis and infestation from parasites.
In one famous case, the Tyrannosaurus rex skeleton nicknamed ‘Sue’ was found to have many holes in its lower jawbone. The holes are similar to injuries seen in modern-day birds infected with a parasite called Trichomonas, which makes it difficult to swallow and breathe.
