Description Size in green compared with selected giant theropods Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, located at the Field Museum of Natural History under the name FMNH PR and nicknamed Sue , measured Historically average adult mass estimates have varied widely over the years, from as low as 4. The forelimbs had only two clawed fingers,  along with an additional small metacarpal representing the remnant of a third digit. The tail was heavy and long, sometimes containing over forty vertebrae , in order to balance the massive head and torso. To compensate for the immense bulk of the animal, many bones throughout the skeleton were hollow, reducing its weight without significant loss of strength. But in other respects Tyrannosaurus’s skull was significantly different from those of large non- tyrannosauroid theropods. It was extremely wide at the rear but had a narrow snout, allowing unusually good binocular vision. These and other skull-strengthening features are part of the tyrannosaurid trend towards an increasingly powerful bite, which easily surpassed that of all non-tyrannosaurids. The D-shaped cross-section, reinforcing ridges and backwards curve reduced the risk that the teeth would snap when Tyrannosaurus bit and pulled.
The name Tyrannosaurus rex means “king of the tyrant lizards”: Aside from Tyrannosaurs, other Tyrannosaurid genera include Albertosaurus, Alectrosaurus, Alioramus, Chingkankousaurus, Daspletosaurus, Eotyrannus, Gorgosaurus, Nanotyrannus a controversial genus that might, in fact, be an adolescent T. But it’s possible that T. An analysis of T. Perhaps the paleo beast crossed over about 67 million years ago when the seaway between Asia and North America receded, the researchers said.
However, the finding is still preliminary, and other experts maintain that T.
Fossils of T. rex are found only in the Hell Creek Formation of Garfield county, Montana, and adjacent areas of the United States, in deposits dating from the Maastrichtian Age, the last time unit of the Cretaceous Period—although slightly earlier relatives such as .

The species Tyrannosaurus rex, commonly abbreviated to T. It hails from what is now western North America. Some scientists consider Tarbosaurus bataar from Asia to represent a second species of Tyrannosaurus, while others maintain Tarbosaurus as a separate genus. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail.
Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small and retained only two digits.

Email The controversial discovery of million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to new research, iron in the dinosaur’s body preserved the tissue before it could decay. The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins — and possibly even DNA — can survive millennia.
Schweitzer and her colleagues first raised this question in , when they found the seemingly impossible: The find was also controversial, because scientists had thought proteins that make up soft tissue should degrade in less than 1 million years in the best of conditions. In most cases, microbes feast on a dead animal’s soft tissue, destroying it within weeks.
The tissue must be something else, perhaps the product of a later bacterial invasion, critics argued. Then, in , Schweitzer and her colleagues analyzed the chemistry of the T.
Mashable In addition to being one of the largest known carnivorous dinosaurs, Tyrannosaurus Rex — or abbreviated as T Rex — is a type of dinosaur that received the most media coverage. T Rex is a member of the family Tyrannosauridae or large predatory dinosaurs with small forelimbs and has two fingers. Besides Tyrannosauridae, the other tyrannosaurs generation includes Prodeinodon, Nanotyrannus, Gorgosaurus, Albertosaurus, Eotyrannus, Daspletosaurus, Alectrosaurus, Chingkankousaurus, Alioramus and Tarbosaurus.
Impressive Figures The T Rex skeleton of the largest and most complete ever found dubbed Sue, named after its discoverer, paleontologist named Sue Hendrickson. The measurements of Sue concluded that T Rex is one of the largest carnivorous dinosaurs ever lived, has a height of 4 meters up to the hips and length of
I wasn’t at all ready for the feelings I’d have about being adopted and queer and raising a toddler who still isn’t as old as I was when I came to the United States on an airplane.
The most famous proponent of the theory today is John R. Horner of Montana State University. According to Horner and other paleontologists, there are lots of reasons why T. Some of the world’s largest flying birds, such as condors , are scavengers — they eat what they find instead of what they kill. By this logic, really big dinosaurs might have been scavengers, just like their really big avian counterparts today. This is mostly speculative, but some aspects of T. Its nasal passages, for instance, are huge, potentially perfect for smelling faraway carrion.
A tyrannosaurus’s teeth and jaw are made for biting — hard. This force could break a bone just like you could break a stick if you bend it with two hands. Paleontologists have also analyzed a coprolite, or a pile of fossilized T. This may mean that the dinosaur relied on picked-over bones for nourishment. To some, the presence of lots of broken teeth also suggests that T.
May 20, ] This is a modified version of an essay that originally appeared on Panda’s Thumb , under the same title. The three page paper in Science magazine, published by the American Association for the Advancement of Science, presents the striking discovery of apparently preserved organic tissues. These include several cell types that the authors feel able to delineate by direct comparison to modern cells recovered from a recent ostrich femur. Within hours of their story’s release creationist email lists and bulletin boards were blazing around the world about the new scientific “proof” of the Earth’s recent creation.
Summer Engagement Photos at Deep River County Park One of my favorite things about wedding days is spending the day with the bride and her bridesmaids. And, this is exactly how I met Jessica. She did a wonderful job of helping Sarah throughout the day, and I was so glad to have met both of the Dienes girls. During the reception, I noticed Jessica on the floor with a handsome guy whom I assumed was her boyfriend.
I saw them sneak a kiss, which confirmed suspicions, and I was sure to grab photos of their sweetness. I would LOVE to photograph their wedding someday! I had the privilege of taking their engagement photos at Deep River County Park in Hobart, Indiana and will have the pleasure of being their wedding photographer next May!
They claim this startling evidence clearly supports a young earth. Even more interesting is what Answers in Genesis omits from the original article, as they “pick and choose,” as is their style, only those portions that supports their position. Carl Wieland of AiG calls this a “stunning rebuttal of millions of years. Instead of focusing only on the soft tissue alone the “straw” , let’s examine the whole picture.

This has changed over the past few decades because of the dramatic advances in digital imaging technologies and computer power. One of the best examples of this was the computer artistry of Ray Downing, whose digital re-creation of Jesus based on the Shroud was documented in “The Real Face of Jesus” program that appeared on the History Channel.
In the past few years, digital artists around the world have been able to render their own interpretations of how Jesus may have appeared based on the Shroud and these show up from time to time on the internet. However, throughout all those years, not one artist has attempted to create an interpretation of what Mary, Mother of Jesus looked like based on the Shroud image. Until now, that is. In July of my good friends Bill and Belenna Lauto directed me to the website of digital artist Dean Packwood in Taupo, New Zealand and shared his beautiful, photorealistic rendition of Mary, Mother of Jesus with me.
Dean chose the Shroud of Turin image as the structural basis for his truly beautiful, completely digital artwork and I wanted to share it with you. So I sent Dean a request for permission to include his painting here on our website and he graciously agreed to share it with us.

Since the last time I blogged , the following things have happened: I had another surgery on my shoulder I stayed extremely sick from whatever I contracted on my trip to Cuba and lost 15 pounds I got two blood clots in my arm, one of which was Deep Vein Thrombosis I started a new job and have spent two separate weeks at the corporate office in Florida Our foster son left suddenly, unexpectedly, and painfully. AJ and I got licensed to become foster parents a year ago. At the time, it seemed like an ideal way to give back to our community, test the waters of parenthood, and move away from being quite as self-centered as we typically are.

Rex Rare footprints indicate a pace of just 3 to 5 miles per hour, but the dinosaur that made them wasn’t in a hurry. Let’s say you travel back in time to the Cretaceous Period and find yourself face to face with a hungry tyrannosaur. Can you outrun the beast? If you believe the headline atop an article describing new research on a set of dinosaur footprints in present-day Wyoming, maybe so.
It reads ” You could probably have outrun a T. The spacing of the rare footprints — each measuring about 18 inches in length — suggests a gait of 4. Story continues below photo. The series of three footprints in sandstone dating back 66 million years are believed to have been made by a young T. The stride length and hip height were plugged into a standard equation to arrive at the estimate of the dinosaur’s gait speed. But it says little about tyrannosaurs’ maximum speed. So just how fast could a T.
Persons said there’s no scientific consensus even after decades of debate. Some say it could manage no more than about 10 miles per hour, others that it could run 45 miles per hour.
