  Plus palaeontologists would’ve picked up on other clues if the bones had large muscles attached to them like a buffalo.

  And the jaw muscles would have to be equally built up to make grabbing and holding make sense, all arm strength no hand strength

  What is the “fin’s” purpose then?

    Display and / or temperature regulation. What’s the ‘purpose’ of any exterior adornment?

      time to compare mass/cooling appendage area for dinosaurs and elephants (they use their ears for cooling).

      problem.

      Weren’t spinosaurs aquatic? cooling surfaces like those aren’t needed if you’re in the water.

        I’m not an expert on these, just pointing out they aren’t made for attaching large neck muscles

    Usually weird protrusions on dinosaurs have to do with sexual distinction, rather then function.

    Even the horns and neck shield on the triceratops are more about sex than about offense/defense

      As continued in modern male birds having the more extravagant displays.

      Part of the evidence for dinosaurs being birds is that female dinosaur bones show the same changes that female birds during their reproductive cycle - they build up like extra blood structures for support iirc.

    Some recent evidence suggests the Spinosaurus may or may not be semi-aquatic. We’ve got a super limited fossil record from this region of Egypt.
