Why dating of fossils is inaccurate

When King Edward VII visited in 1902, he reportedly asked that a similar dinosaur be put on display at the natural history branch of the British Museum (now the Natural History Museum, London).Carnegie passed the request back to his people in Pittsburgh, initially making the fairly unrealistic request that somebody go dig up another skeleton.Despised in the West and revered in the East, dragons have a long history in human mythology. No one knows the exact answer, but some myths may have been inspired by living reptiles, and some "dragon" bones probably belonged to animals long extinct — in some cases dinosaurs, in others, fossil mammals.

In short, Owen saw the dinosaur as quadrupedal, with a mammalian-like stance.

The realization that Adding to its lizard-like appearance was a row of spikes running down its back. Rudwick This is a close-up view of the pterodactyles in the previous picture.

Later sauropod articulations raised the heads, and even later ones raised the tails after paleontologists realized that few signs of tail dragging appeared in dinosaur tracks.

As for sauropods spending most of their time in the water, by Barrett, Parry and Chapman At the beginning of the 20th century, Andrew Carnegie was dividing his time between the United States and Scotland, and spending his vast fortune on philanthropic projects.

That discovery didn't occur for decades after this picture was published, and water-dwelling dinosaur persisted throughout much of the 20th century. portrayed the animal alternately as a lawnmower and a reptilian version of a hippo, frequently wallowing in the water.

This early sketch of the dinosaur shows it near what appears to be a mudflat.

Paleontologists debated pterosaur posture and locomotion on the ground for many years after Owen and Hawkins produced these sculptures, and the scaly necks reflect the understanding that the animals were indeed reptiles.

More recent finds indicate that, although pterosaurs had scales, they were confined to the feet and maybe the legs. Rudwick Waterhouse Hawkins drew this diagram for a lecture he delivered to the Society of Arts in London, and the picture mapped the planned placement of the ancient reptiles in Crystal Palace Park.

He reported hearing reports of "an immense and wholly unknown animal" in Rhodesia, and legends of "a huge monster, half elephant, half dragon." He was a bit fuzzy about his sources, but his casual speculation nevertheless spawned headlines, including "Brontosaurus Still Lives" in the . Over a century later, despite the complete lack of physical evidence to vouch for the animal's existence, many cryptozoologists and creationists still cling to the Mokele Mbembe legend.

Internet Archive ( Richard Owen, perhaps for theological reasons, insisted upon a mammalian articulation in dinosaur reconstructions but, decades later, Hay argued that dinosaurs had alligator-like stances and drooping abdomens.

Instead, he saw reptiles from the Mesozoic as much more like modern mammals. Grindon's knobby monstrosity retains Owen's limb proportions and association with the wrong tracks, but also gives the ancient amphibian rear legs that protrude above the torso like a pair of spider legs.
