Any info on fukuiraptor? Preferably weight range.

That’s certainly not a giant theropod by any standard. The holotype is the largest specimen, and it’s estimated at 4.2m in lenght and may be ~250kg in mass. Now apparently all specimens, that one included, are immature, so there’s no precise way of saying how large an adult would be, but Azuma & Currie suggested it was already close to adult size.

Cool! Only about two months left if the "August" stands for the release date (at least I don't know what else it could mean). |

I know its not theropid but I really needed to know. Thank you.

The Das Monster von Minden has finally been described. It's named Wiehenvenator albati. And it still belongs to this thread, it's still far larger than the average theropod  __ I attempted a GDI of Scott Hartman's Sue. Looks like I got quite close to his volume estimate

I feel obliged to write a profile, someday.

Well, what size is the average theropod? And are we including 10 000 species of birds that are all under 100kg in that figure? In any case, Wiehenvenator is large, Allosaurus-sized maybe, certainly among the biggest terrestrial predators we have from Europe (excluding the maker of some of the large Asturias and Lourhinha trackmakers, which would most likely dwarf it), although whether I’d call it a giant theropod is up for debate. But since things can change rapidly anyway the broadest definition might be the best. Btw they really found Liopleurodon teeth just a few metres away from the Monster, IIRC a pliosaur was an early speculation to explain the association of very large teeth and it seems to hold true (none of the referred theropod teeth are anywhere near as huge as some early rumours, but Liopleurodon might have a shot). As for the alledgedly gigantic ribs, no idea what inspired that claim, but maybe one could get the impression that they are gigantic if the Allosaurus ribs used for comparison were from a juvenile, or by comparing thoracic ribs to abdominal ones…
Donald Henderson made a 3D-restoration of Spinosaurus and presented it at SVPCA, the abstract’s here: to be found here: svpca.org/query/query.phpIIRC creature already posted it elsewhere, I just thought it belonged here. I’ve got some doubts about the exact figures, although it is very well possible that it does not affect the conclusions, since estimating airspace volume in Spinosaurus based on birds and assigning a fixed density for everything else ignores its noticeably denser bone structure and lack of post-cervical pneumaticity, very much unlike in birds or other coelurosaurs, but that probably doesn’t affect the main point here; Apparently the "centre of mass" estimated by Ibrahim et al. was the centroid of the shape they wrapped their skeleton in, without any regard to varying densities due to pneumatic structures in the anterior part of the body. |

I feel obliged to write a profile, someday. Evidently, that didn't take very long to formulate. |

The average theropod was estimated at between ~100-1000 kilograms by Farlow, 1993, "On the rareness of big, fierce animals: speculations about the body sizes, population densities, and geographic ranges of predatory mammals and large, carnivorous dinosaurs". The actual average is probably closer to the lower bound of the range, given that the smaller-bodied taxa far outnumber the larger-bodied ones in both population size and number of taxa, and that preservational bias favors larger-bodied taxa. |

Height: 4-5m
Weight: 5000kg
I wonder why they still state such weird figures.
