Cranial ornamentation linked with dinosaurs’ gigantic size

Dinosaurs, including Tyrannosaurus, Allosaurus, and Giganotosaurus all were having ornamented skulls. A new research has unveiled that these cranial ornaments were not only fashion statements, but they also had a role to play in the overall size of these predators.

Study’s lead researcher Terry Gates, a paleontologist at North Carolina State University and the North Carolina Museum of Natural Science noticed a strange pattern. He saw that many of the larger theropods were having bony cranial ornamentation, but it was missing among the smaller theropods.

Scientists unveil unique camouflage pattern used by Psittacosaurus

Dinosaur fossils discovered in the recent years have offered very interesting information about various species that thrived the planet in the past and Psittacosaurus fossil presents a unique camouflage patterns noticed in any dinosaur species for the first time. Scientists have carried out a detailed assessment of a well-preserved Chinese Psittacosaurus fossil. After the fossil analysis, they have come to know that the dinosaur had a defense mechanism that has been never seen before in any other dinosaur species.

Researchers reconstruct life-size 3D model to know about long-lost species Psittacosaurus

A new set of information has been revealed about a well-preserved dinosaur from China named Psittacosaurus, meaning parrot lizard. The dinosaur, which lived around 120 million years ago, most probably had a dense, dark forest as its habitat. Also, it boasted of a defense mechanism not seen in any other dinosaur earlier.

Study researchers have shared that the parrot lizard like many modern animals used a form of camouflage known as counter-shading. The dinosaur had lighter shade underbelly with darker shade on the top.

3.7-billion-year-old fossils found in Greenland act as oldest physical evidence of life on earth

Fossils dating back 3.7 billion years and termed as the oldest physical evidence on earth have been discovered in Greenland. If the findings turn out to be true then they would act as a treasure trove providing vital information on ancient living organisms as well clues about similar sings of possible ancient life forms on planet Mars.

3.7-billion-year-old remnants of microbial mats claimed to be oldest fossils ever seen

A journal Nature-published research paper has unveiled about the discovery of 3.7-billion-years-old fossils, the remnants of microbial mats, claimed to be the oldest fossils ever found. If the findings are confirmed then the established fossil record would be pushed over 200 million years deeper into earth’s early history.

Another thing that would be provided with the confirmation is life appeared soon after earth formed. A team of Australian geologists has made the discovery in July 2012 while carrying out field research in Isua, a remote place in Greenland.
