Some very quick Spinosaurus mirabilis sketches & notes

DISCLAIMER:

I'm no palaeontologists, I haven't even read the paper yet! The suggestions of biomechanics are just based on my quick, unprofessional observations. To me, S.Mirabilis seems to rely more on the jaw muscles while S.aegypticus relies more on its neck muscles & sheer weight. That is because, based on the comparison diagrams. the jugals (? If that's the right name?) of S.mirabilis seems proportionally more robust than S.aegypticus, who in return has teeth more foreward facing for ensnarement. Again, not a scientist! This is just armchair guessing.

Qantassaurus intrepidus Body Study Based on the skeletal model from the Australian Museum / Wikipedia image for Quantassaurus.

Oops, dino hyperfixation! I didn't check for the correct musculature, so don't take this as super accurate. The background was also just thrown together quickly.
