Where are most fossils found
sedimentary rock
Most fossils "hide out" in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock.
What is fossil
Fossils are the geologically altered remains of a once-living organism and/or its behaviour. There are two main types: body fossils represent all or part of the organism's body, and trace fossils show evidence of the organism's behaviour.
What dinosaur is still alive
birds
In the view of most paleontologists today, birds are living dinosaurs. In other words, the traits that we accept as defining birds — key skeletal features as well as behaviors including nesting and brooding — actually arose first in some dinosaurs.
Are dinosaur bones real
The "dinosaur bones" that you see on display at the Museum aren't really bones at all. Through the process of fossilization, ancient animal bones are turned into rock.
How old is the oldest fossil
3.5 billion years old
Cyanobacteria: Fossil Record. The cyanobacteria have an extensive fossil record. The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old!
Do fossils have DNA
(In fossils, minerals replace the once-living parts of the body like bone and tissue, so DNA isn't preserved.) “[With] humans, plants, other animals and microbes, there are a number of questions that can only be answered with DNA and not with a fossil record,” says Llamas.
Is there still a dinosaur still alive
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
What dinosaur died last
Johnson told Discovery News that he agrees the Triceratops is indeed "the last known non-avian dinosaur of the Cretaceous." He said, "The 3M Gap is a weak concept to begin with," and that his own work on plants and insects supports the idea that the meteor impact was the "direct and immediate cause of habitat …
Did T. rex eat bones
Scientists have long known that T. rex ate bones, as indicated by the fragments found in fossilized dinosaur dung. Bones, particularly the yolk-like marrow inside, are rich in nutrients.
Where is Sue the T. rex
Field MuseumSue / Where to view
SUE is the largest and most complete Tyrannosaurus rex skeleton ever discovered, at more than 40 feet long. The fossil, one of the most famous in the world, has its permanent home at the Field Museum in Chicago.
What is the oldest human found
Lucy, Ethiopia, 3.2 Million Years Ago
Found in Hadar, Ethiopia, Lucy is the oldest and most complete human fossil ever found, making up 40% of a complete human skeleton. She was dated at 3.2 million years old and was a hominid with clear evidence of being bipedal (two-legged).
How old is the oldest rock
about 4.0 billion years
The oldest in-place Earth rock is thought to be from the Acasta Gneiss in the Canadian Shield. Scientists use dating techniques on the zircon crystals in the rock, determining the age of this rock to be about 4.0 billion years.
Does dinosaur DNA still exist
The bonds that hold it together are weak and, over time, they break down. This is why, even though we have an abundance of dinosaur fossils, we don't have any dinosaur DNA. The beasts died out 66 million years ago, and the DNA would simply not survive that long.
Can we recover dinosaur DNA
DNA breaks down over time. The dinosaurs went extinct around 66 million years ago and with so much time having passed it is very unlikely that any dinosaur DNA would remain today. While dinosaur bones can survive for millions of years, dinosaur DNA almost certainly does not.
Who killed the last dinosaur
The last non-bird dinosaurs were living at a time of environmental change, some of which began millions of years before they went extinct. The asteroid was the final, killer blow.
When was the last dinosaur killed
about 65 million years ago
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Is there 1 dinosaur still alive
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
What dinosaur has 500 teeth
Nigersaurus
Bizarre 500-toothed dinosaur
Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago. This sauropod (long-necked dinosaur) has an unusual skull containing as many as 500 slender teeth.
What dinosaur killed the T. rex
Crumbles. Its mighty head falls through the riverbed. And the life leaves its eyes by slipping on the bank the rex's own body weight snapped its neck while the giga simply just held its grip.
Is Sue the dinosaur a boy or girl
Even though we refer to SUE as a “she,” it is unknown whether this T. rex was female or male. We know that this carnivorous dinosaur lived about 67 million years ago and probably weighed nine tons during its life.
Is Sue dinosaur real
Sue is the nickname given to FMNH PR 2081, which is one of the largest, most extensive, and best preserved Tyrannosaurus rex specimens ever found, at over 90 percent recovered by bulk. FMNH PR 2081 was discovered on August 12, 1990, by American explorer and fossil collector Sue Hendrickson, and was named after her.
How old is Lucy the first human
3.2 million-year old
Figure 1: Lucy's skeleton. Lucy, a 3.2 million-year old fossil skeleton of a human ancestor, was discovered in 1974 in Hadar, Ethiopia. The fossil locality at Hadar where the pieces of Lucy's skeleton were discovered is known to scientists as Afar Locality 288 (A.L.
Is Lucy still the oldest human fossil
Scientists today announced the discovery of the oldest fossil skeleton of a human ancestor. The find reveals that our forebears underwent a previously unknown stage of evolution more than a million years before Lucy, the iconic early human ancestor specimen that walked the Earth 3.2 million years ago.
How is the oldest rock
In 1999, the oldest known rock on Earth was dated to 4.031 ±0.003 billion years, and is part of the Acasta Gneiss of the Slave craton in northwestern Canada.
What rock is the oldest rock
The oldest minerals from Earth's crust yet discovered are the zircons found in Archean metamorphosed sedimentary rock from the Jack Hills of southwestern Australia. Analysis of the zircon consistently provides dates over 4.0 Ga with the oldest being 4.4 Ga.
