Buy Dinosaur Shakespeare: To Date or Not To Date?
Scientists on Wednesday said the dinosaur, named Siamraptor suwati, was more than 26 feet 9 meters long and weighed at least 3. Siamraptor, the largest carnivorous dinosaur ever discovered in Thailand, lived during the Cretaceous Period in an environment centered on a meandering river system and preyed on plant-eating dinosaurs, the researchers said.
The fossils include parts of the skull, backbone, limbs, hips and teeth. The teeth of dinosaurs in this group boasted traits resembling those of a shark, enabling efficient flesh-tearing. The earliest carcharodontosaurs are known from even-older fossils from Africa and Europe, leaving the researchers surprised to find an early member of the group in Southeast Asia.
A fossil is any preserved remains, impression, or trace of any once-living thing from a past The development of radiometric dating techniques in the early 20th century allowed has been the discovery of soft tissue in dinosaur fossils, including blood vessels, and the isolation of proteins and evidence for DNA fragments.
Neatly dressed in blue Capri pants and a sleeveless top, long hair flowing over her bare shoulders, Mary Schweitzer sits at a microscope in a dim lab, her face lit only by a glowing computer screen showing a network of thin, branching vessels. From a dinosaur. It was big news indeed last year when Schweitzer announced she had discovered blood vessels and structures that looked like whole cells inside that T.
The finding amazed colleagues, who had never imagined that even a trace of still-soft dinosaur tissue could survive. After all, as any textbook will tell you, when an animal dies, soft tissues such as blood vessels, muscle and skin decay and disappear over time, while hard tissues like bone may gradually acquire minerals from the environment and become fossils. Schweitzer, one of the first scientists to use the tools of modern cell biology to study dinosaurs, has upended the conventional wisdom by showing that some rock-hard fossils tens of millions of years old may have remnants of soft tissues hidden away in their interiors.
And the new findings might help settle a long-running debate about whether dinosaurs were warmblooded, coldblooded—or both. They claim her discoveries support their belief, based on their interpretation of Genesis, that the earth is only a few thousand years old. Growing up in Helena, Montana, she went through a phase when, like many kids, she was fascinated by dinosaurs. In fact, at age 5 she announced she was going to be a paleontologist.
But first she got a college degree in communicative disorders, married, had three children and briefly taught remedial biology to high schoolers. In , a dozen years after she graduated from college, she sat in on a class at Montana State University taught by paleontologist Jack Horner, of the Museum of the Rockies, now an affiliate of the Smithsonian Institution.
The lectures reignited her passion for dinosaurs. She initially thought she would study how the microscopic structure of dinosaur bones differs depending on how much the animal weighs.
How and why to date a dinosaur
Dinosaurs used to live in New Zealand. We know this because their fossils have been found in a few places. They were found together with fossils of land plants, including pollen from trees and tree ferns, as well as with fossil marine animals. The remains of dead land animals and plants were probably washed down a river and into a shallow bay, where they mixed with the remains of dead marine animals. This material was compressed together with sediments into a sandstone rock.
James and the other paleontologists used relative dating first, which looks at where rocks fit in a sequence.
Aug 25, – Mummified dinosaur skin that has since fossilized. Dating to the Cretaceous, this spectacular fossil originates from the Hell Creek Formation.
Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages. Knowing when a dinosaur or other animal lived is important because it helps us place them on the evolutionary family tree. Accurate dates also allow us to create sequences of evolutionary change and work out when species appeared or became extinct.
There are two main methods to date a fossil. These are:. Where possible, several different methods are used and each method is repeated to confirm the results obtained and improve accuracy. Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date. A common problem with any dating method is that a sample may be contaminated with older or younger material and give a false age.
This problem is now reduced by the careful collection of samples, rigorous crosschecking and the use of newer techniques that can date minute samples.
A fossil from Classical Latin : fossilis , literally “obtained by digging”  is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons , stone imprints of animals or microbes , objects preserved in amber , hair, petrified wood , oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.

Dating dating relies on the properties of isotopes. These are chemical elements, like carbon or uranium, that are identical except how one fossils feature — the number of neutrons in their nucleus. How dinosaur have an dating number of protons and neutrons. If, however, there are how many or too few date, the atom is unstable, dating it sheds particles until its date reaches a stable state. Think of the nucleus as a fossils of building blocks.
