You're looking at the only known fossilized skeleton of a sauropod dino called "Amargasaurus", recovered from the La Amarga Formation in Argentina. One of the smallest sauropods at 13 m in length & 2-4 tons in weight, the distinctive 'neural spines' projecting from the vertebrae are a puzzle.

I read "Amargasaurus" and wondered why it was named the "bitter lizard" until it became clear it was a location name. Now I need to go look up why someone in New Spain named a place the bitter formation. 😄

When I see things like this I turn into a little kid again, fascinated with dinosaurs and wishing I could make friends with them. Like big dogs.

Kinda interesting how many species evolved raised spines but in different ways and in different niches. Acrocanthosaurus wiki says it might have supported muscles, but why don't other theropods have them? Seems like there's a new Spinosaurus paper every week, so I won't even speculate
