Morphospecies theory says t-rex was king carnivore at all stages of life

Morphospecies theory says t-rex was king carnivore at all stages of life

A study released this week shows how the tyrannosaurus consumed different resources at multiple stages of growth. Modern meat-eating mammals can easily be arranged in a chart showing average adult size - each of these animals have a unique effect on their own ecosystem. Given the average size of adult dinosaurs, there appeared to be a massive gap in the middle of the chart from smallest to largest.

UT researchers definitively link asteroid impact with the demise of the dinosaurs

UT researchers definitively link asteroid impact with the demise of the dinosaurs

Researchers from the University of Texas at Austin say they believe they have definitively closed the case of what killed off the dinosaurs. The team definitively linked the extinction of the dinosaurs to an asteroid that impacted the earth 66 million years ago. The link came when the team found a key piece of evidence in the form of asteroid dust inside the Chicxulub Crater in the Yucatán Peninsula in Mexico.

Harvard researchers have a new theory on what killed the dinosaurs

Scientists know that about 66 million years ago, a major event happened on earth that resulted in the extinction of the dinosaurs. The Chicxulub impactor, as the impact is known, left behind a massive crater off the coast of Mexico 93 miles wide and 12 miles deep. While scientists know this is the impact that made many species on Earth at the time go extinct, there is debate about exactly what the Chicxulub impactor was and where it came from.

Four-year-old Welsh girl discovers dinosaur footprint at the beach

Four-year-old Welsh girl discovers dinosaur footprint at the beach

Scientists are always looking for more information about dinosaurs as some details can be hard to discern from fossils that are already available. A four-year-old girl from Wales was at the beach with her father and her dog when she discovered an extremely well-preserved dinosaur footprint. The fossilized footprint is so well preserved that paleontologists around the world are excited to study it.

All-purpose dinosaur opening reconstructed by University of Bristol scientists

All-purpose dinosaur opening reconstructed by University of Bristol scientists

A team of scientists from the University of Bristol has described in detail the cloacal or vent of a dinosaur. The cloaca is an all-purpose opening dinosaurs used for defecation, urination, and breeding. Researchers on the project note that most mammals have different openings for these functions, but most vertebrate animals possess a cloaca.

Prehistoric “Sea Dragon” fossil discovered in the English Channel

Prehistoric “Sea Dragon” fossil discovered in the English Channel

Researchers discovered a new prehistoric sea creature nicknamed the "Sea Dragon" and officially named the Thalassodraco etchesi. The small marine reptile lived 150 million years ago during the Late Jurassic era and appears to be evolved to dive to extreme depths. The fossilized creature was discovered in the Late Jurassic deep marine deposit along the English Channel coastline in Dorset, England.

Scientists are looking for the world’s oldest ice in Antarctica

Scientists are looking for the world’s oldest ice in Antarctica

Scientists are working in Antarctica and believe that the continent holds the world's oldest ice. They believe ice on the continent is hundreds of thousands or even millions of years old. Exactly how old the ancient ice could be, scientists don't know. They aren't sure how long ice could survive.

Bizarre fossil discovered of a mammal that roamed with the dinosaurs

Bizarre fossil discovered of a mammal that roamed with the dinosaurs

Researchers have discovered the fossilized remains of a strange creature that roamed the earth in the distant past. The creature has been named Adaltherium and is believed to represent an important piece in the puzzle of early mammalian evolution in the southern hemisphere. The bizarre creature is 66 million years old, and scientists believe it provides insights into the evolutionary history of mammals in the ancient southern supercontinent of Gondwana.

Paleontologists say mass extinctions on Earth follow a 27 million year cycle

Paleontologists say mass extinctions on Earth follow a 27 million year cycle

Recently paleontologists have discovered something that many will find rather chilling. According to new research, mass extinctions of land-dwelling animals, including amphibians, reptiles, mammals, and birds, follow a cycle spanning about 27 million years. Interestingly, this mass extinction cycle also coincides with previously reported mass extinctions of ocean life. The study has found that mass extinctions align with significant asteroid impacts and volcanic eruptions on Earth.

Dinosaurs weren’t in decline before the asteroid hit the Earth

Dinosaurs weren’t in decline before the asteroid hit the Earth

A new analysis has been performed by researchers at the University of Bath and the Natural History Museum London that refutes the claim dinosaurs were in decline before the massive asteroid impact that led to the extinction of most species on Earth. The researchers believe that had the asteroid impact not happened, dinosaurs may have continued to dominate the Earth. At the time of the asteroid impact at the end of the Late Cretaceous period, dinosaurs were widespread globally.

Duckbill dinosaur fossils discovered in Africa for the first time

Duckbill dinosaur fossils discovered in Africa for the first time

Scientists working in Morocco have discovered the very first apostles of a duckbilled dinosaur ever found in Africa. The findings suggest that the dinosaurs crossed hundreds of kilometers of open water to reach Africa after evolving in North America and migrating to South America and then Asia, Europe, and Africa. A study on the findings was recently published in Cretaceous Research.

Baby t-rex bones are first of their kind and kinda cute

A study published this week showed a pair of tyrannosaurus rex fossils that are the sort that've never been found before. At least, not by modern humans that had any idea what they were looking at. Such is the way of things, when it comes to objects millions of years old: Sometimes you just don't know what you've got, because how on earth could you?
