Max Daeodon (Blaze) vs Ceratosaurus dentisulcatus (Hartman) How did you scale those??? The scalebar in blaze ’s skeletal is 50 cm, that in Hartman’s 100 cm, yet for some reason the former is 16 or 17 px, while the latter is 65 or 66 px. The Daeodon should be about twice this size. You can actually see this with the naked eye, the Daeodon in your comparison looks like it’s barely a metre tall at the shoulder. |

The Daeodon is about 1.8 meters SH while the Ceratosaurus is 8.8 meters |

The Daeodon is less than 1.2 m SH based on your scalebar, while the Ceratosaurus is 6.7 m, quite reasonably sized (there’s only one specimen that might be slightly larger than that, but not anywhere close to 8.8 m, more like 7 m).

I didn't use the scalebars; I used another size chart to scale which is not in the screenshot.
And the 8.8 meter Ceratosaurus is inaccurate?

Got any evidence it is accurate?
The only Ceratosaurus specimen I know of that may be larger than the one depicted by Hartman is BYUVP 12893, accoding to Mortimer’s figures.

What I actually meant by that is that I did not know if it was inaccurate or not.
I'll rescale the 2 and post a better size chart later.

Unless stated otherwise, it is generally assumed that reconstructed specimens have the dimensions intended by whoever made the reconstruction. There often isn't even a point in arguing against them, as a specimen with a different size might have different proportions.

I suppose that's true. That's why I don't scale an AMNH 2057 to Sue size or vice versa if I was going to do a chart

Also, generally speaking, if the largest specimens of a species have good remains, most people doing skeletals preferentially depict them (part of the somewhat unreasonable fixation with maximum size in palaeontology). So if you know nothing else, at least consider that the specimen as depicted by the author might actually reflect the maximum, or at least a large specimen, and if it significantly differs from the size you read somewhere on the internet, maybe be a little skeptical of the latter and check the figure.
As for Ceratosaurus, I’d suggest you go see if you can find reliable information on BYUVP 12893 (there is supposed to be a paper on it, but I didn’t read it). Mickey Mortimer estimates it at 7.1 m. Since her listed size for the specimen Hartman depicts agrees with Hartman, that might be reasonable, or else, find a better figure.
