Fossil hunters digging the soil near a creek in north-central Illinois have come across a remarkable discovery — Tully monster. They have found the preserved remnants of a prehistoric creature, which appears to be having a long, arm-like appendage extending from below with a pincer-like mouth and its wide-set eyes pointed towards stalks.
Scott Lidgard, a paleontologist at Chicago’s Field Museum, said the Tully monster, which is Illinois’ official state fossil, beyond doubt was “very, very bizarre”.

Tyrannosaurus rex, a 40 feet long behemoth killer dinosaur, topped the food chain over 70 million years ago. However a new study has revealed that in the state, the size of tyrannosaurs species was small, comparable to humans. The evolution of species into a much bigger size has surprised paleontologists.
Paleontologists unearthed a fossil in Uzbekistan, which revealed missing link in the evolution of T. rex. The fossil belongs to a tyrannosaur, which had characteristics like a T. rex, but it wasn’t 40 feet long.

A sample of new fossil has been found at Bailey Quarry outside Windsor. Researchers have stated that it resembles to pine tree, which are found mostly in Northern Hemisphere forests these days. The fossil was discovered in the quarry in Mantua by Dr. Howard Falcon-Lang, of Royal Holloway, University of London.

Ichthyosaurs, an iconic group of marine predators from the dinosaur era, mysteriously met their demise before the mass extinction took place. Now, a study has unveiled as to what could have been the factors behind their end. The study team has blamed climate change and lack of diversity among ichthyosaurs to be the reasons.

Boston College researchers have uncovered the worldwide spread of an ancient group of retroviruses that affected ancestors of roughly 28 of 50 modern mammals nearly 15 to 30 million years back.
Retroviruses are widespread and consists human immunodeficiency viruses (HIV-1 and -2) and human T-cell leukemia viruses. The findings of the scientists on a particular group of these viruses known as ERV-Fc have shown that they affected a large number of hosts, like species as diverse as primates, carnivores, and rodents. The results will appear in journal eLife.

Researchers have discovered fossils of terrestrial fungi that may have played an important role in supporting early ecosystem at the time when our world was much different what we see today. The study on life of Tortotubus protuberans fungi, the world’s oldest terrestrial fossils, was published in the Botanical Journal of the Linnaean Society on Wednesday.
The oldest fossils came from North Africa, they date back to 445 million years, while most recent are about 385 million years old. The second oldest fossil is 5 million years younger than Tortotubus.

American Museum of Natural History (AMNH) researchers were surprised when they analyzed Smilodon, a saber-toothed cat during a study on feeding among clam-eating marine carnivores. However, from their recent findings the elusive cat had a jaw structure resembling that of a marine bear, which existed 20 million years ago. Both species were meat-eaters.

The fossil of a shrimp-like animal that thrived on our planet 520 million years ago has given researchers an opportunity to understand ancient nervous system. The remains unearthed from southern China are so well preserved that individual nerves are still visible.
A study team reported that it is one of the best preserved nervous systems ever discovered. It has been estimated that the ancient nervous system could reveal several things about animals’ evolution.

Freshly published research paper about genetic data backs up the long-thought belief that glyptodonts are part of armadillos. The DNA study published in Current Biology has proved that the long-extinct armored beasts were very closely related to modern armadillos.
Study researchers Hendrik Poinar of McMaster University and Frédéric Delsu of the French National Centre for Scientific Research have assessed the genome of a Glyptodont called Doedicurus, which was one of the largest known species in the family.

The Rapa Nui Island, famous for its homogenous stone statue called Moai, was named Eastern Island during its discovery by a Dutch explorer Jacob Roggeveen in 1722. Once it was home to civilization of monolithic era that later became extinct. Many archeologists have different views regarding what led to the demise of Rapa Nui. Two possible answers to the question by historians and archeologists are in conflict with each other.
