A possibly 15 m long carnosaur ("Osteoporosia") that is known since six years, but not properly described yet? Sounds cool.

^They claimed they got that figure by analogy with Aerosteon, which they claimed was 9m long. Since that’s likely an overestimate, we should account for that. E.g. since Hartman’s Neovenator is ~7.65m in axial length, and its ilium is ~71cm long, from isometric scaling to its ~77cm ilium we’d expect Aerosteon to be short of 8% larger, or 8.23m. |

Thanks! (I already heard about the problems with Aerosteon, but I must have forgotten them or I simply did not pay enough attention to the methodology)
Using the corrected length would still yield roughly 13-14 m, but as this still has many characteristics of a guesstimate (and is particularly problematic due to the uncertain classification of Osteoporosia, "carnosaur" doesn't tell a lot), I of course won't give it much consideration. That doesn't mean I'm not looking forward towards a proper description (and hopefully also a proper classification) of that dino.

"Osteoporosia"?
Wow...just wow...

Given that they always set "Osteoporosia" in quotation marks, I guess it is so far a mere nickname. A proper name is something else we can hope for.

Osteoporosia would actually be a tyrannosauroid if it was really an Aerosteon-like form, since, well, megaraptorans are tyrannosauroids now.

The material referred to "Marocannoraptor", a supposedly ~4.5 meter long Unenlagine dromaeosaur actually belongs to an indeterminate crocodyliform according to Cau on his latest blog post.
Another giant, 12+ meter long theropod from the Kem Kem? Wow. Just when I though I'd seen everything.
Plus, it's a potential tyrannosauroid too. This is interesting indeed!
Though I remember Cau demonstrating that since the Cenomonian spans 6 million years, and the Kem Kem beds represent a scarce representation of the fauna, it's unlikely that every single theropod found in the Cenomonian sediments actually coexisted with one another since the average survival time for a species is usually just 0.5 to 2 million years.

If everything that's been hinted at about this theropod is true, well...guess who'd no longer be the only heavy hitter in its superfamily  . |
