Iguanodon v Baryonyx

Baryonyx walkeri
Baryonyx was the first carnivorous dinosaur to be discovered in England. It was an unusual theropod with huge foot-long claws on its hands. Most theropods had S-shaped necks, but Baryonyx had a long straight one that was fairly inflexible. The design of its hips and pelvis suggests that it was bipedal for the purposes of walking from place to place. However, its forelimbs were absurdly large for a theropod, suggesting that it also spent much of its time on all fours. It had a long long tail and a low-slung body. Skull & Jaws: The skull was set at an acute angle, not the 90° angle common in similar dinosaurs. The long jaw was distinctly crocodilian, and had 96 teeth, twice as many as its relatives. Sixty-four of the teeth were placed in the lower jaw (mandible), and 32 large ones in the upper (maxilla). The snout probably bore a small but distinctive crest. Baryonyx was about 2.60–2.75 m (8 ft 6 in–9 ft 0.3 in) tall, 9.5 m (31 ft) long, and weighed in the region of 1,700–2,700 kg (3,700–6,000 lb). However, analysis of the bones suggests that the most complete specimen was not yet fully grown, so Baryonyx may have grown even larger.

Iguanodon bernissartensis
Iguanodon ( /ɪˈɡwɑːnədɒn/ i-gwah-nə-don; meaning "iguana-tooth") is a genus of ornithopod dinosaur that lived roughly halfway between the first of the swift bipedal hypsilophodontids and the ornithopods' culmination in the duck-billed dinosaurs. Many species of Iguanodon have been named, dating from the Kimmeridgian age of the Late Jurassic Period to the Cenomanian age of the Late Cretaceous Period from Asia, Europe, and North America. However, research in the first decade of the 21st century suggests that there is only one well-substantiated species: I. bernissartensis, that lived from the late Barremian to the earliest Aptian ages (Early Cretaceous) in Europe, between about 126 and 125 million years ago. Iguanodon's most distinctive features were its large thumb spikes, which were possibly used for defence against predators, combined with long prehensile fifth fingers able to forage for food. Iguanodon were bulky herbivores that could shift from bipedality to quadrupedality. The only well-supported species, I. bernissartensis, is estimated to have weighed about 3 tonnes (3.5 tons) on average, and measured about 10 metres long (33 ft) as an adult, with some specimens possibly as long as 13 metres (43 ft). These animals had large, tall but narrow skulls, with toothless beaks probably covered with keratin, and teeth like those of iguanas, but much larger and more closely packed.

Baryonyx = 8.5 meters long, 1700 kilograms
Iguanodon(average size, in green) = 10 meters long, 3000 kilograms
Iguanodon(maximum size, in red) = 13 meters long, 6591 kilograms(scaled from avg. sized specimen)

LOL at anyone who thinks Baryonyx can win this...
This ladies and gentle men is the WORST size comparison between 2 animals I have ever seen in my entire life...
if that baryonyx is 8.5 metres long then the 12 metre iguanodon is 15 metres long and the 10 metre is around 10.5-11 metres long in this comparison.

any way I obviously vote for iguanodon for obvious reasons.

That red iguanodon looks spinosaurus-sized.

I admit that I've mis-scaled the dinosaurs. Anyway, that's an old comparison, and shouldn't be used as reference.

Baryonyx was found with Iguanodon remains in its stomach, although there is the possibility that it had been scavenging.
In a simple face-to-face fight I favour Iguanodon on account of its size advantage, thumb spikes and overall power.

Iguanodon almost always wins. Its too big for Baryonyx to fatally wound. The Iguandon remains found in its stomach were most likely from scavenging or possibly from a young Iguanodon.

Charig and Milner (5) indicate the presence of the acid-etched remains of a young
specimen
of the plant-eating ornithopod dinosaur Iguanodon in the body cavity of Baryonyx, so it almost
certainly fed on the meat of terrestrial animals as well as fish.

Alright, I definitely support Iguanodon nearly 100% of the time now.

Iguanodon wins due to size.
