First fossil proof found that long-necked dinosaurs were vegetarians
In the movie 'Jurassic Park,' a character proclaims there is nothing to fear from a towering Brachiosaurus, because it's a 'veggie-saurus' that eats only plants. Littlefoot, the 'Longneck' dinosaur in the 'Land Before Time' series, eats leaves, or 'tree stars.' But although pop culture and general scientific opinion have agreed for decades that the long-necked sauropod dinosaurs were herbivores, there was no definitive proof found in the fossil record.
But there were hints of a diet full of green stuff.
Fossils of sauropods, which stomped across the planet for 130 million years, are plentiful; additionally, herbivores tend to outnumber those of carnivores. The animals had small, peglike teeth, and their huge, lumbering bodies seemed ill equipped to chase down prey. 'Plants were pretty much the only option,' said Stephen Poropat, a paleontologist and the deputy director of the Western Australian Organic and Isotope Geochemistry Center at Curtin University in Perth.
A study published in the journal Current Biology provides what may be the first concrete proof to support this argument, in the form of fossilized plants discovered in the belly of a sauropod. 'It's the smoking gun, or the steaming guts, as it were — the actual direct evidence in the belly of the beast,' Poropat said.
Poropat, along with scientists and volunteers from the Australian Age of Dinosaurs Museum, encountered the fossil on a dig in Queensland, Australia, in 2017. — KATE GOLEMBIEWSKI ?NYT
