What about Apatosaurus/Brontosaurus? I can't tell them apart.

What about Apatosaurus/Brontosaurus? I can't tell them apart.

Brontosaurus has a more narrow space between the bifurcated neural spines, longer pubis, an overall shorter length of spine from neck to tail, more a more square shaped coracoid, shorter cervcial ribs, and a far less robust neck and forelimbs.
There are likely more differences I'm missing but the differences are there.

Thank you for the breakdown. I was fully aware of differences existing per se (even if I didn't know which ones), but I still don't think I'd be able to externally differentiate them.

Well, as long as the people working with Brontosaurus and Apatosaurus can tell the differences, then they're distinct

Oh I wasn't really implying that they're the same creature, but rather that they could be different species within the same genus.

Manospondylus gigas would have been Tyrannosaurus rex's senior synonym if not for Nomen Protectum being established on the more scientifically important name
