Perhaps not quite complete... I don't remember having seen allosaurus and carcharodontosaurus.

" Allosaurus, meaning "different delicate reptile," is a theropod (meat-eating dinosaur) that probably ate other smaller dinosaurs. Its teeth were up to 3 in (7.6 cm) long and serrated like steak knives for cutting flesh. Adults hunted by overpowering their prey, possibly in small groups. Juvenile Allosaurus relied on their longer limb bones that were better adapted to running in order to hunt smaller vertebrates. Even though Allosaurus grew up to 30 ft (8.5 m) in length, it was not the largest predator of the time. Its sharp teeth and hook-shaped claws did, however, make Allosaurus a nightmare for many creatures of the Jurassic."

" Daspletosaurus (meaning "frightful lizard") was a genus of tyrannosaurid dinosaur that lived in western North America between about 77 and 74 million years ago, during the Late Cretaceous Period. The genus Daspletosaurus contains two species. Fossils of the earlier type species, D. torosus, have been found in Alberta, while fossils of the later second species, D. horneri, have been found only in Montana. A possible third species, also from Alberta, awaits formal identification. (Daspletosaurus sp.) Daspletosaurus is closely related to the much larger and more recent tyrannosaurid Tyrannosaurus rex. Like most tyrannosaurids, Daspletosaurus was a multi-tonne bipedal predator equipped with dozens of large, sharp teeth. Daspletosaurus had the small forelimbs typical of tyrannosaurids, although they were proportionately longer than in other genera.
As an apex predator, Daspletosaurus was at the top of the food chain, probably preying on large dinosaurs like the ceratopsid Centrosaurus and the hadrosaur Hypacrosaurus. In some areas, Daspletosaurus coexisted with another tyrannosaurid, Gorgosaurus, though there is some evidence of niche differentiation between the two. "

Carcharodontosaurus skull / size?
Carcharodontosaurus is a genus of carnivorous carcharodontosaurid dinosaurs that existed during the Cenomanian stage of the mid-Cretaceous Period. It is currently known to include two species: C. saharicus and C. iguidensis, which were among the larger theropods, nearly as large as or even larger than Tyrannosaurus, Giganotosaurus and Spinosaurus.
Carcharodontosaurus includes some of the longest and heaviest known carnivorous dinosaurs, with various scientists proposing length estimates for the species C. saharicus ranging between 12 and 13.3 m (39 and 44 ft) and weight estimates between 6.2 and 15.1 metric tons. In 2016 Molina-Pérez & Larramendi gave a length of 12.8 metres and a weight of 7.8 tonnes for C. saharicus, and a length of 11 metres and a weight of 5.2 tonnes for C. iguidensis.
Carcharodontosaurus were carnivores, with enormous jaws and long, serrated teeth up to eight inches long. A skull length of about 1.53—1.6 meters (5.0—5.2 ft) has been restored for C. saharicus, and the skull of C. iguidensis is reported to have been about the same size.

On the skull of Carcharodontosaurus saharicus, it is imporant to remember that the skull was incomplete and missed the front part, this is from the original document of Sereno et al., (1996):
*This image is copyright of its original author
As we can see, the front and the back is fully recontructed, but not all people is agree. In fact Scott Harman call that a "Pinocchio nose" as is too much elongated with no reason.
Even then, the authors estimated that the skull measured about 1.6 meters in length and that figure is still supported, but Franois made a reconstruction without the long nose and got a length of 1.53 m, which is not far from the figure of Sereno and team:

Finally the reconstruction of Carcharodon saharicus made by Franois, updated at 2018:
*This image is copyright of its original author
As we can see, very few is know of this animal and the more complete holotype specimen is completelly lost in the WWII. So, some people reconstruct it longer, other shorter but base in the explanation of Franois himself, I can agree that this reconstruction is the most accurate one from this giant African predator, the true apex carnivor of northern Africa and a real menace for any animal in the area, including the fish-eater Spinosaurus.
By the way, C. iguidensis was smaller than the neotype of C. saharicus.

"In 2016 Molina-Pérez & Larramendi gave a length of 12.8 metres and a weight of 7.8 tonnes for C. saharicus, and a length of 11 metres and a weight of 5.2 tonnes for C. iguidensis."
I searched a little about those authors and actually that is mainly a book for young people and far for been an academic/reliable source of information, although the pictures are amazing.
I found these links, as the book is originally published in Spanish:
http://apegoyliteratura.es/resena-records-y-curiosidades-de-los/
https://www.deviantart.com/asier-larramendi/art/Records-de-los-dinosaurios-teropodos-portada-637987384
The book have excelent pictures, but to be honest is not a good source for sizes, practically copy-paste many of the old records and did not follow the new studies about body masses, so is like your average "Dinosaur book". That is why I prefer the original scientific papers now, for somer reason Dinosaur books are many times full of inaccuracies.

" Acheroraptor, by rapthor - deviantart "
Acheoraptor is the youngest specy of dromaeosaurids, dated to 66 millions years. Discovered in the Hell-Creek formation (Montana) among bones of t-rex, triceratops, edmontonia and so on. From a complete right maxilia and a referred dentary.
