The Plateosaurus at the Snorre offshore field had a hollow grave. The fossil, which was found 2256 metres below the seabed, represents the world’s deepest dinosaur finding.
What depth are fossils found?
Theoretically you can find fossils 20 kilometer deep, though they might be a little hot. Actually the deepest found fossil depends on the deepest mine, which is Mponeng Gold Mine in South Aftrica with 4km.
How do dinosaur bones end up underground?
The most common process of fossilization happens when an animal is buried by sediment, such as sand or silt, shortly after it dies. Its bones are protected from rotting by layers of sediment. As its body decomposes all the fleshy parts wear away and only the hard parts, like bones, teeth, and horns, are left behind.
What is the deepest fossil found?
BBC NEWS | Science/Nature | North Sea fossil is deepest dino. The first dinosaur fossil discovered in Norway is also the deepest one that has been found anywhere in the world. The 195-210-million-year-old specimen was found 2.3km (1.4 miles) below the floor of the North Sea by an offshore oil drilling platform.
Does a fossil have to be 10000 years old?
What is a fossil? Fossils are the remains and/or traces of prehistoric life. The critical factor is age. Fossils have to be older than 10,000 years, the generally accepted temporal boundary marking the end of the last Pleistocene glacial event.
Are dinosaurs still alive?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
How do dinosaurs die?
The dinosaur-killing crash threw huge amounts of debris into the air and caused massive tidal waves to wash over parts of the American continents. There is also evidence of substantial fires from that point in history. For a long time it was thought that the non-bird dinosaurs died out 65 million years ago.
Why didnt dinosaur bones decompose?
When a dinosaur bone is encased in sedimentary rock, the moisture from the surrounding sediment infuses the bone with these minerals. … After the process is undergone for millions of years, there isn’t really any bone left and the only way for the fossil to “deteriorate” is for it to wear down through erosion.
Where are the real dinosaur bones kept?
Ever wondered where they keep all those dinosaur bones? Just below the American Museum of Natural History large dinosaur bones are stored and researched in the Big Bone Room.
Can I keep a fossils you find?
If you find a dinosaur fossil on private land, it’s yours to do with as you please. In the United States, the fossilized remains of the mighty creatures that lived in eons past are subject to an age-old law—”finders keepers.” In America, if you find a dinosaur in your backyard, that is now your dinosaur.

fossils and the remains of vertebrate animals (those with a backbone). The US federal land laws forbid any collection of vertebrate fossils without an institutional permit, but allow hobby collection of common invertebrate and plant fossils on most federal land , and even commercial collection of petrified wood.
What was found in the deepest man made hole?
The 23-centimetre (9 in) diameter boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262 metres (40,230 ft; 7.619 mi) in 1989, the deepest artificial point on Earth.
Kola Superdeep Borehole.
|Greatest depth||12,262 metres (40,230 ft; 7.619 mi)|
When the first fossil was found?
In 1822, Mary Ann Mantell, who was married to geologist Gideon Mantell, discovered fossilized bones while on a walk in Sussex, England. Further examination found that they looked similar to an iguana skeleton, so the “fossil reptile” was aptly named Iguanodon.
What was the biggest underwater dinosaur?
But now, scientists have finally unearthed the heaviest known elasmosaur, an ancient aquatic reptile that swam the seas of the Cretaceous period alongside the dinosaurs. The animal would have weighed as much as 15 tons, and it is now one of the most complete ancient reptile fossils ever discovered in Antarctica.
