The Brontosaurus is back, baby!

Brontosaurus

After years of the Flintstones lying to me, I’d just gotten used to the idea of the Brontosaurus not actually being a dinosaur. But a recent study of the classifications given to various species and genera within the diplodocid group of dinosaurs has determined that the Brontosaurus and the Apatosaurus are different enough to be two separate species.

Very broadly, their tree confirmed established ideas about the evolutionary relationships among diplodocids. But the scientists also concluded that Apatosaurus and Brontosaurus were different enough to belong in their own genera. Many of the anatomical differences between the two dinosaurs are obscure, Tschopp says, but Apatosaurus’s stouter neck is an obvious one. “Even though both are very robust and massive animals, Apatosaurus is even more so,” he adds.

Tschopp and his team thought very carefully about their decision to reinstate Brontosaurus, and they expect some pushback. “We knew it would be a major finding because Brontosaurus is such a popular name,” he says. “I’m pretty sure there will be a scientific discussion around this. I hope there will be. That’s how science works.”

Huzzah! Now reinstate Pluto to full planetary status and we’ll be all set. See also The Kindly Brontosaurus. (via @coudal)
