Discovery sets June air date for Half Yard’s “Dino Hunters”
Produced by Half Yard Productions, a Red Arrow Studios company, the series features characters like Clayton Phipps from Montana, who was born into cattle ranching and discovered the greatest fossil specimen uncovered in America, Dueling Dinosaurs — foot-long theropod and a foot-long ceratopsian fossils — and now searches for fossils with his year-old son Luke and a small team of fossil experts. The elder Harris, Mike, discovered a T-Rex in , and now his adult son Jake has returned to the ranch to hunt for dinosaurs together. Each episode will see the characters uncovering new fossil discoveries, with the clock ticking to excavate before the harsh winter ruins their chances at a potential fortune; as well, the dinosaurs will be brought back to life with 3D modeling and CGI to create X-ray visualizations of the fossils and dinosaurs.

Forget Extinct: The Brontosaurus Never Even Existed
Age bias continually colors the interpretation of dinosaur fossils. How do we know secular analyses are flawed? Is there evidence that confirms dinosaurs lived recently? Full-Bible Christian.
In the all new series DINO HUNTERS, cowboys and ranchers rely on their to other ranchers who sit on fossil-rich badlands dating back 65 million years. of his career was dashed by a contract dispute with the landowner.
Scientists determine most precise dates yet for dinosaur extinction 66 million years ago. Rock strata in northeastern Montana; they span the time of the dinosaur extinction. This material is available primarily for archival purposes. Telephone numbers or other contact information may be out of date; please see current contact information at media contacts. In an attempt to resolve the issue, scientists at the Berkeley Geochronology Center BGC at the University of California, Berkeley, and at universities in the Netherlands and the United Kingdom, have determined that an impact event occurred at about the same time as the mass extinction of the dinosaurs.
Using a recalibrated technique for dating Earth minerals, the researchers hypothesize that impact happened 66,, years ago, and that it produced the final atmospheric conditions needed to wipe out the dinosaurs. The newly determined date of the impact is the same, within error limits, as the date for the mass extinction event, which also occurred about 66 million years ago, according to Paul Renne, BGC director.
The dates are so close, the researchers say, that it was likely that a comet or asteroid that, if not wholly responsible for the global extinction, at least dealt the death blow. But it probably wasn’t just the impact. The revised date clears up lingering confusion over whether the impact actually occurred before or after the extinction, which was characterized by the almost overnight disappearance from the fossil record of land-based dinosaurs and many ocean creatures, Renne said.
Renne decided to recalculate the date of the boundary between the Cretaceous and Tertiary periods–the KT boundary–after recalibrating the argon-argon method used to date rocks, which relies on the decay rate of a radioactive isotope of potassium.
What Really Killed the Dinosaurs?
If you watched for an hour or two, the star would have seemed to grow in brightness, although it barely moved. Sixty hours later, the asteroid hit. The air in front was compressed and violently heated, and it blasted a hole through the atmosphere, generating a supersonic shock wave. In that moment, the Cretaceous period ended and the Paleogene period began.
The result was a slow-motion, second-by-second false-color video of the event.
Tyrannosaurus rex, along with every other dinosaur except the ancestors of element found in asteroids, in sediments dating to the time of the extinction. like much of science — is complicated, controversial and captivating.
All data generated or analysed during this study are included in the manuscript and supporting files. Cretaceous dinosaur bone contains recent organic material and provides an environment conducive to microbial communities. Saitta ET. Dataset for Taphonomic research on organic material in Cretaceous dinosaur bones. Field Museum collections.
Fossils were thought to lack original organic molecules, but chemical analyses show that some can survive. Dinosaur bone has been proposed to preserve collagen, osteocytes, and blood vessels. Subsurface dinosaur bone is a relatively fertile habitat, attracting microbes that likely utilize inorganic nutrients and complicate identification of original organic material. There exists potential post-burial taphonomic roles for subsurface microorganisms.
The chances of establishing a real-world Jurassic Park are slim. During the fossilization process, biological tissues degrade over millions of years, with some types of molecules breaking down faster than others.
Incomplete T. Rex Fossil Leads to Contract Dispute
Apatosaurus right, opposite a Diplodocus skeleton at the Carnegie Museum of Natural History in Pittsburgh , is what paleontologist Othniel Charles Marsh actually found when he thought he’d discovered the Brontosaurus. It may have something to do with all those Brontosaurus burgers everyone’s favorite modern stone-age family ate, but when you think of a giant dinosaur with a tiny head and long, swooping tail, the Brontosaurus is probably what you’re seeing in your mind. Even if you knew that, you may not know how the fictional dinosaur came to star in the prehistoric landscape of popular imagination for so long.
It dates back years, to a period of early U. Othniel Charles Marsh was a professor of paleontology at Yale who made many dinosaur fossil discoveries, including the Apatosaurus — and the fictional Brontosaurus.
Even if you knew that, you may not know how the fictional dinosaur came to two Carnegie researchers took a second look at the controversy.
The last dinosaurs died approximately 65 million years ago. Although the cause of their extinction is still a mystery, climatic change, diseases, changing plant communities, and geologic events could all have played a role. Lately, dinosaur extinction theories have been the subject of much debate and controversy.
A recent explanation, supported by many scientists, suggests that dinosaurs died out soon after a huge meteorite crashed to Earth near the Gulf of Mexico. Without the sun, all the plants died; without the plants, all the plant-eaters died; and without the plant-eaters, all the meat-eaters died. Sounds reasonable. But there is one problem with this theory: Paleontologists have not yet been able to find dinosaur skeletons in rocks dating to the period of impact.
Some evidence even seems to indicate that all the dinosaurs had died before the meteorite hit.
From herding to hunting: New Discovery series Dino Hunters highlights cowboys making history
While something involving dinosaurs and radioactive decay might sound like the reanimation of Godzilla , there is something about the tiny Pisanosaurus could mean a monster discovery. The most infamous kaiju of all time is a dinosaur that emerged from the depths of the ocean after being zapped back to life by nuclear radiation. Isotopes of lead that resulted from radioactive decay of uranium revealed that it appeared around a critical time in evolution. The team is now convinced that this species goes all the way back to when the first dinosaurs walked the Earth.
Dinosaurs, which share a common ancestor, diverged into saurischians lizard-hipped and ornithiscians bird-hipped around million years ago. Preserved in this site were the fossils of some of the earliest known dinosaurs, which had scientists believing that dinosaurs first appeared in what is now South America when it was still part of Pangaea.
Precise dating of geological formations is especially critical for testing This might be seen as controversial, since generally dinosaur taxa are.
Are the results a confirmation of rapid formation of the geologic column as modern sedimentology studies have predicted? Key Words : Radiocarbon dating, dinosaur, bone collagen, organic carbon, bone bio-apatite, fossil wood, amber, megafauna. Bone collagen and soft tissue were recently reported as having been discovered in a Tyrannosaurus dinosaur femur bone as well as other fossil bones from the Cretaceous period of the geologic column by Mary H.
Schweitzer et al. According to Dr. Libby, the inventor of the radiocarbon dating method, ” There is no known natural mechanism by which collagen may be altered to yield a false age. It is common practice to determine the age of bones by radiocarbon RC dating of extracted bone collagen but not of dinosaurs because they are assumed to have become extinct 65 million years BP and, therefore, too old for RC dating.
The data was challenged by Thomas Stafford as poor science due to assumed contamination from modern C with younger surficial calcium carbonate. Bone bio-apatite can be unreliable due to potential contamination from calcium carbonate replacement containing modern or dead carbon [unless carefully pretreated]. However, a study of the cm.
The extinction of the dinosaurs has long been considered a crime committed by a lone gunman: an incoming asteroid that struck the earth 65 million years ago, filling the air with sun-blocking dust. Now, however, controversy is being stirred anew as evidence suggests that the asteroid might have had a partner in crime: volcanoes, massive ones, blasting clouds of toxic gas from the bowels of the earth and poisoning much of the planet’s life. It was nearly 30 years ago that physicist Luis Alvarez and his son Walter, a geologist, proposed the giant-impact theory of dinosaur extinction.
Their evidence was compelling: a thin layer of iridium in the earth’s sediment dating to about the time of the die-off.
A summary of theories among paleontologists about why dinosaurs became extinct. extinction theories have been the subject of much debate and controversy. yet been able to find dinosaur skeletons in rocks dating to the period of impact.
A few days ago, a follower of mine gave me an interesting read from The Atlantic regarding the dinosaur extinction. Like many of my generation, I was taught in school that dinosaurs died because an asteroid hit the Earth. Yes, I am a proud parent. Now I have to do a sit-down with the child and explain that… What, exactly? The volcanoes were located in India and they erupted for hundreds of thousands of years, but most violent eruptions, Keller thinks, were in the last 40, years before the extinction.
This hypothesis is called the Deccan volcanism from the region in India where these nasty volcanoes are located, first proposed by Vogt and Courtillot et al. So which is true? The impact hypothesis was put forward in when Walter Alvarez, a geologist, noticed a thin layer of clay in rocks that were about 65 million years old, which coincided with the time when the dinosaurs disappeared. This layer is on the KT boundary sometimes called K-T, K-Pg, or KPB, looks like the biologists are not the only ones with acronym problems and marks the boundary between the Cretaceous and Paleogenic geological periods T is for Triassic, yeah, I know.
Walter asked his father, the famous Nobel Prize physicist Louis Alvarez, to take a look at it and see what it is. Alvarez Sr. After gathering more samples from Europe and New Zealand, they published a paper Alvarez et al.
