The is my reconstruction of the Giganotosaurus carolinii specimen MUCPv-95 which was discovered in 1987 and described by Calvo in 1989. Although it was recognised that the specimen belonged to a very large theropod dinosaur it was never assigned a name. However in 1995 when the specimen Mucpv Ch1 was described by Coria and Salgado as Giganotosaurus carolinii the specimen MUCPv-95 was assigned to the genus in 1998 by Calvo and Coria. Mucpv Ch1 was around 70 percent complete and was estimated to be between 12.25 and 12.41 meters in length. Mucpv-95 was around 2.5 to 8 percent larger than Mucpv-95 so scaling linearly would place its estimated body length at around 13.23 meters. So this would place its estimated weight at around 8616 kg, heavier than the largest specimen of Sigilmassasaurus/Spinosaurus MSNM v 4047 at around 7600 kg but not quite as heavy as the Tyrannosaurus specimen FMNH PR 2081 at 8830 kg. Of course, it’s impossible to accurately determine the total body size of an animal from a single left dentary so it’s possible that the specimen wasn’t actually this large rather it just possessed a proportionally larger head. So take this size estimate with a pinch of salt but if it is accurate than this would make Giganotosaurus the second largest theropod dinosaur.
Of course Giganotosaurus is one of the most over hyped dinosaurs discovered, not quite to the extent T. rex is but pretty close. The media at the time described it as the largest theropod dinosaur ever, Bigger than T.rex! Size estimates of 14 meters, 15 meters and even 16 meters were tossed around. Unfortuantly Giganotosaurus has experienced a downsizing since then but it is still a very impressive theropod. Giganotosaurus has also made a fair few appearances in pop culture, appearing in Dino Crisis 2, Journey to the Centre of the Earth, Primeval, Chased by Dinosaurs, Ark: Survival Evolved and Jurassic World Evolution. Giganotosaurus is fairly well known to the public and I’m glad that this dinosaur has become an icon of pop culture. When I was growing up Giganotosaurus was my favourite dinosaur and even today it still is one of my favourites.
This unusual large mammal lived in North America during the
Pleistocene epoch until the end of the ice age. It roamed the earth
for over a million years, but suddenly disappeared (perhaps because of the climate changes). It was one of the largest land animals living during the ice age. Mastodon belonged to the family Mammutidae, that originated in North Africa, spreading to Eurasia and entering North America 15 million years ago. Its name means "nipple tooth". These elephant-like animals were affected by environmental changes. Mastodons living during the middle of the last glaciation were small, whereas those living later in forests were larger. It was mostly adapted to conifer forests and marsh. It fed on plants (conifer twigs, swamp plants, larch, spruce, pine, grass, mosses, etc.) and used its tusks to break branches.
