Here's T rex vs some of North America's biggest sauropods. Looks like Rexy no longer holds the crown! Holotype of Tyrannosaurus rex (CM 9380, 11.9 meters axial length, 7.5 tonnes), holotype of Sauroposeidon (OMNH 53062, 32 meters TL, 60 plus tonnes), BYU 9024 Barosaurus (50 meters TL, 100 tonnes), and OMNH 1670 Apatosaurus adult size (37 meters TL, 100 tonnes). Scalebar column is 1 meter each, skeletals by Hartman, Paleo King, Hartman, and Hartman.  |

Here's 2 of the beefiest giant sauropods in a size comparison. Futalognkosaurus holotype (MUCPv-323, 27 meters TL, 60 tonnes) vs OMNH 1670 Apatosaurus (29.8 meters TL, 52 tonnes). Neither sauropod is full grown. Side views are by Paleo King and Scott Hartman respectively, top views by Paleo King and Greg Paul respectively. Left scalebars are 1 meter.  |

The two unlabeled creatures are Anomalocaris spp. One is A. canadensis, the other is A. giganteus (which is apparently a dubious species). I'm sure readers can make out which is which.  |

Here's 2 of the AMNH's specimens in a size comparison. American mastodon (AMNH 9950, 289 cm SH, 7.8 tonnes) vs Tyrannosaurus rex (AMNH 5027, 11.8 meters TL, ~6 tonnes). Side views are by Larramendi and Hartman, top view for the mastodon is by Larramendi while the Tyrannosaurus rex top view is modified from Hutchinson 2011.  |

Here's one that just came to mind yesterday:
Acrocanthosaurus vs Tarbosaurus, both largest estimates.

roninwolf1981, here you go - largest specimens of Acrocanthosaurus and Torvosaurus that I am aware of, scaled to 129 and 150 cm skull respectively. Skeletals by Franoys and Scott Hartman respectively.

That's a good scale, but I said Tarbosaurus, not Torvosaurus.

Oh, yes you did. That was my bad.
I'll make a new one ASAP with TARBOSAURUS, not Torvo.

roninwolf1981 , here. Largest specimens of Tarbo and Acro, 152 and 129 cm skulls respectively. Skeletals by Franoys.

Man, they're almost perfectly matched...
I would think that Tarbosaurus has more stability with his stance, given how his hips are built, compared to the Acrocanthosaurus.

Well, Acrocanthosaurus would probably be the more stable one - it's got shorter, stockier legs and a large ridge of muscle to anchor the support.
I do agree it's almost perfect though.

USNM 6183 (17 years of age, 99 cm femur, based on LACM 23845) vs MUCPv-95 (13.2 meters axial length, 8.6 tonnes). Scalebar is 1 meter, skeletals by Franoys and GetAwayTrike.  |

Triceratops vs Apatosaurus (AMNH 5040 vs YPM 1840) Triceratops is scaled to 275 cm skull and is probably >14-15 tonnes, while Apatosaurus is based on CM 3018 and scaled to 243 cm femur (~31.3 meters TL, 60.5 tonnes). Left scalebar is 1 meter, side view skeletals by GetAwayTrike and Hartman while both top views by Greg Paul.  |
