Lengths are best-estimate midpoints, drawn to scale.
Did they ever meet?
No. Baryonyx lived about 130 to 125 million years ago in what is now England and Europe, some 25 to 30 million years before Spinosaurus, though the two were close spinosaurid relatives.
The verdict
A family matchup, and a lopsided one on size. Both were spinosaurids that fished with long, narrow jaws, but Spinosaurus was roughly twice the length and several times the weight of Baryonyx. On size Spinosaurus wins comfortably. Baryonyx is best seen not as a rival but as a smaller, earlier glimpse of how the spinosaurid fishing lifestyle began.

Was Baryonyx related to Spinosaurus?
Yes. Baryonyx was a spinosaurid, part of the same family as Spinosaurus, and shared the fish-catching jaws and claws, though it was much smaller and lived earlier in Europe.
