At 59 tonnes, plant-eating dinosaur had 'the largest reliably calculable weight' of any known land animal. The dinosaur Dreadnoughtus weighed 59,300 kilograms and measured 26 metres long. It was
Did Dinosaurs Lay Eggs Individually? Today's paleontologists tend to agree that different dinosaur species laid different amounts of eggs. While some species produced around 1 to 5 in a single sitting, others produced around 15 to 20. Paleontologists have even discovered one type of dinosaur, the psittacosauru s, that laid around 35 eggs at a
The hundreds of specimens obtained from the La Brea Tar Pits in Los Angeles constitute the largest collection of Smilodon fossils. S. gracilis was the smallest species at 55 to 100 kg (120 to 220 lb) in weight. in length indicates this individual may have weighed as much as 436 kg (961 lb). It stood at a shoulder height of 120
The 50-Foot-Long, 2,000-Pound Giant Prehistoric Snake, Titanoboa. Titanoboa was a true monster among prehistoric snakes, the size and weight of an extremely elongated school bus. Research has indicated that the giant snake looked like a boa constrictor āhence its nameābut hunted like a crocodile. Here are the top nine pieces of trivia about
This leaves teeth as the only common fossils from which scientists can compute the size for this massive shark. Most current, scientifically accepted estimates for the Megalodon's maximum size fall into the 60-70 foot range, with a weight of 50-70 tons. Compare that to the Great White Shark that maxes out at about 21 feet and 3 1/2 tons.

Its length and weight are estimated at 15 metres (about 50 feet) and 45 tonnes (almost 100,000 pounds), respectively. The jaws of this creature are thought to have produced a bite force of 33,000 psi (pound-force per square inch), perhaps the largest bite force of any known animal.
Quick Facts. Historical Period: Late Jurassic (155-145 million years ago) Size and Weight: About 90 to 120 feet long and 25 to 50 tons. Distinguishing Characteristics: Enormous body; quadrupedal posture; long neck with relatively small head. The Seismosaurus is one of the biggest dinosaurs in size.
Ankylosaurus was one of the largest ankylosaurs, with a total length of up to 10 metres (33 feet) and a probable weight of about four tons. Its head was square and flat and was broader than it was long. Its teeth, like those of the related stegosaurs, consisted of a simple curved row of irregularly edged (crenulated) leaf-shaped teeth.The body was short and squat, with massive legs to support
The reason for the smaller size is unknown. The average female has been estimated to have had a shoulder height of 2.3 m (7.5 ft) and a weight of 2.8 tonnes (3.1 short tons) in the Siberian populations and a shoulder height of 2.6 m (8.5 ft) and a weight of 4 tonnes (4.4 short tons) in the European populations.
This would not, incidentally, have been the only known dinosaur vs. crocodile cage match. (If it did in fact prey on dinosaurs on a regular basis, that would go a long way toward explaining the exceptionally large size of Deinosuchus, as well as the enormous force of its bite: about 10,000 to 15,000 pounds per square inch, well within

Allosaurus, which predated Tyrannosaurus Rex by some 85 million years, was the largest land predator of the late Jurassic Period. The 38-foot long, 17-foot tall Allosaurus even towered over fellow predators like the horn-nosed Ceratosaurus, who was a fairly intimidating 10-12 feet in height and 15 to 20 feet in length.
The Nation's T. rex was 38 feet (11.6 meters) long, and scientists estimate that it weighed 4-5 tons, which is about 8,800-11,000 pounds. How complete is the Nation's T. rex ? It is one of the most complete T. rex specimens ever found, with approximately 85 percent of the skeleton preserved.
An early and not especially large sauropod, it lived 160 million years ago, laid eggs and possibly lived in a herd. It weighed 13 tons and ate 1,150 pounds of vegetation a day. The model focuses
