Not sure of the weights. I'll wait for theropod.

How about Eustreptospondylus vs Cryolophosaurus then?

Dracorex vs Alectrosaurus:
This is the most complete specimen of Alectrosaurus olseni, the others are only isolated teeth-of course not a good base for size estimations as tooth position cannot always be determined:
Quote:
 
(AMNH 6554) two manual unguals(?), pubic foot fragment, femur (647 mm), tibia (732 mm), proximal fibula, astragalus (77 mm wide), calcaneum, metatarsal I (~62.8 mm), phalanx I-1 (61.3 mm), pedal ungual I (43.4+ mm), metatarsal II (460.7, 470.7 mm), phalanx II-1 (114 mm), phalanx II-2 (88.2 mm), pedal ungual II (35.2+ mm), metatarsal III (486 mm), phalanx III-1 (109.5 mm), phalanx III-2 (83.2 mm), phalanx III-3 (67.5 mm), pedal ungual III (38 mm), metatarsal IV (478.2 mm), phalanx IV-1 (~79.6 mm), phalanx IV-2 (~67 mm), phalanx IV-3 (52.5 mm), phalanx IV-4 (38.9 mm), pedal ungual IV, metatarsal V (109.9+ mm)


Let´s use the femur and compare it to A. sarcophagus. I´ll take ROM 807 as a base, which has a femur lenght of 1,02m and is estimated as 8,6m in total lenght.

The total lenght yielded by an isometric downscale is 5,6m. We can assume a weight estimate basing on it might be approximately correct, even if the animal had more slender proportions making it longer.

The weight The theropod database gives seems high for theropod database and an animal that lenght, at 2,5t. The corresponding weight estimate for Alectrosaurus would be 690kg.

All I found about Dracorex hogwartsia is this from wiki:

Quote:
 
The excavated specimen was most likely a young adult. However, based on the beginning of ossification of the mid-cervical arch with the centrum, it was near maturity.[1] The animal was approximately 10 feet (3 m) long.

If this would have still grown a bit, it would still be far far far far far far... smaller than Alectrosaurus, regardless of how we estimate their absolute weight figures.


For the others:

Eustreptospondylus vs Cryolophosaurus

Cryolophosaurus was ~7m long and overally very slender, being a Dilophosaurid. I remember it was estimated at below 500kg by the theropod database, which might be too low when regarding the common estimates for other Dilophosaurs, but still you can see it was anything but bulky. I´d say it definitely didn´t approach 1t, and comparing it to a bit higher estikmates for dilophosaurus it probably maxed out at around 500-700kg.

Eustreptospondylus oxoniensis on the other hand is only known from a single subadult specimen nearly 5m long
Quote:
 
(OUM J13558) (4.63 m, 218 kg; subadult)

Here again the weight figure seems very low, one would expect higher ones for a Megalosaur that size, especially when comparing it to the aforementioned figure for Albertosaurus. The adult size often said to be 7-8m is mere speculation, so I wouldn´t recomment making a matchup in which it is totally unclear how large one of the combatants could get.

Shaochilong vs Teratophoneus
Shaochilong:
Quote:
 
(IVPP V2885.1) (~5-6 m; ~500 kg; adult)

Brusatte et al., 2009:
Quote:
 
All elements seem
to represent a single individual, based on size, matching
articulations, and/or shared phylogenetic affinity



Teratophoneus
Quote:
 
(BYU 826/9402) maxilla
.... (BYU 8120/9396) lacrimal, partial jugal, frontal, squamosal, quadrates (198.2, 199.8 mm), basisphenoid, basioccipital, prootic, exoccipital-opisthotic, partial supraoccipital, articular, third(?) cervical vertebra, partial mid caudal vertebra (~96 mm), scapula, coracoid
....(BYU 8120/9397) humerus (241.9 mm), ulna (140.6 mm)
....(BYU 9398) dentary
....(BYU 13719) femur (757 mm)

Going by the femur Teratophoneus is ~6,4m long and likely bulkier than the Carcharodontosaur. Teratophoneus is 74% Albertosaurus´ linear dimensions and thus only 40% its cubic ones.

I whished there were more measurements here. What I can definitely say is that Teratophoneus was 6,6-28% longer and likely more than 21-109% heavier, so I´d say this might be a size mismatch depending on which sizes we take and which builts we assume...

Sorry that's a weight mismatch. Seeing that there's already a thread involving Albertosaurus v Deinocheirus.

Even though the Diplodocus is much larger, many members would still say the Tyrannosaurus would win rolleyes

The Elephant weight is just a range, that would also mean Spinosaurus and T-rex are at the same weight, but they aren't (Spino is heavier).
