Armadillos are mammals, so probably more like convergent evolution and not an ancestor

Glyptodon are mammels too, and a direct ancestor of armadillos! The -don in the name does imply dinosaur, so I can see why one would make the assumption.

They are not direct ancestors of extant armadillo species, but they are themselves armadillos.

Thanks, I was confusing it with Ankylosaurus

The "don" suffix just means tooth, so it doesn't necessarily have to do with dinosaurs; there are a number of mammalian genera that got it, like Smilodon, Daeodon, Dorudon, and Thrinaxodon
