African Lion - Panthera leo The lion (Panthera leo) is one of the four big cats in the genus Panthera, and a member of the family Felidae. With some males exceeding 250 kg (550 lb) in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in Sub-Saharan Africa and in Asia with an endangered remnant population in Gir Forest National Park in India, having disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru. The lion is a vulnerable species, having seen a possibly irreversible population decline of thirty to fifty percent over the past two decades in its African range. The African lion is a very large cat, with males weighing between 330 and 550 pounds and females weighing between 260 and 400 pounds. It is 8 to 10 feet long, not including the tail. Its most famous feature is its mane, which only male lions have. The mane is a yellow color when the lion is young and darkens with age. Eventually, the mane will be dark brown. The body of the African lion is well suited for hunting. It is very muscular, with back legs designed for pouncing and front legs made for grabbing and knocking down prey. It also has very strong jaws that enable it to eat the large prey that it hunts. ![]() Marshosaurus bicentesimus Marshosaurus was a genus of medium sized theropod, with a size up to 5 or 6 meters (16 to 20 feet) in length and a skull about 60 cm (2 feet) long. It is known from parts of at least three (possibly four) individuals from the Morrison Formation of Utah and Colorado. The holotype is a left ilium, or upper pelvis bone found at the Cleveland-Lloyd Quarry in central Utah. It was named by James Madsen (1976) for Othniel Charles Marsh, who described many dinosaur fossils during the Bone Wars. The species name was chosen "in honor of the bicentennial of the United States of America". Characters on the skeleton show it was an avetheropod, a member of Avetheropoda, a group of more bird-like theropods including Tyrannosaurus, Velociraptor and Allosaurus. Benson (et al., 2009) found it to be a megalosauroid, using a lot of new characters of new Megalosaurus specimens. It lived during the Kimmeridgian (Late Jurassic), approximately 155 - 150 mya. One right ilium of a Marshosaurus bicentesimus is deformed by "an undescribed pathology" which probably originated as a consequence of injury. Another specimen has a pathological rib. In a 2001 study conducted by Bruce Rothschild and other paleontologists, 5 foot bones referred to Marshosaurus were examined for signs of stress fracture, but none were found. ![]()

I think this is an excellent matchup. The lion is more stable, lower to the ground, and has excellent grappling skills accompanied by a set of fairly powerful jaws. But unlike what some people believe, I don't believe the theropod is greatly outgunned. Marshosaurus too will have a damaging bite, and being a megalosauroid, it has long forelimbs with huge claws. Theropods with usable forelimbs (ex: megalosauroids, allosaurids, Acrocanthosaurus) have very robust and muscular arms, just like the lion (it wouldn't be just the arm muscles, also the pectoralis and shoulder muscles helping). I need a size comparison to confirm this, but weapon size (most likely in favor of the dinosaur) could also come into play here, and given it's body plan, I wouldn't be surprised if the theropod was somewhat visually larger, though again, a size comparison is needed. Edit: the dinosaur does have bigger weapons. Marshosaurus bicentesimus wins. Edited by Ausar, Jun 27 2014, 07:25 AM.

if marshosaurus really did grow to 5 to 6 meters in length, than it would of weighed a good amount more than 250kg, though if it really weighed 200-250kg, then i see a close fight. http://scotthartman.deviantart.com/gallery/?offset=48#/art/Marsh-s-Reptile-211970681?_sid=50d431b8 marshosaurus seems to have had formidable weaponry, though the lion also possesses formidable weaponry. i might give the slight edge to the lion since it is a quadraped, which makes it more stable. however, if marshosaurus had a decent size advantage, then i would favor it. edit: i now favor the theropod, though only slightly.

i think you should of used scott hartman's skeletal of marshosaurus instead. furthermore, greg paul estimated its length at 4.5 meters. |

what we also must consider is that marshosaurus skull is around 60 cm in length. thats one hell of a large skull. quite compatible with that of large hippos. not to mention that marshosaurus skull was fairly robustly built. a large skull and a pleasent hight advantage would be quite a useful asset to have for pressing an attack

Am I the first one to say mismatch? You're pitting a theropod against a cat; the results will seldom be in favor of the lion. Marshosaurus has too much of a height and mass advantage. |

i'm not calling it a complete miss match. remember, their at similar weights( maybe. theres still a very good chance of marshosaurus being the larger animal). but i also favor the theropod. it's visually the larger animal with slightly more versatility in it's weaponry then the cat. that large head is a good indacating factor. might i also add those long arms and huge thumb claws are also going to make any attempt for the lion to grapple down the thropod very unpleasent p.s- i love your velvet worm signature |

have fun trying to get pass that head and hight. again, it's the same length as a large hippo and quite robustly built. and even then, marshosaurus had very long arms tiped with large thumb claws, very well equipted to create large gashes Edited by spinosaurus rex, Apr 14 2014, 03:20 AM.

As well as possibly the hindlimbs.
