Researchers propose radical overhaul of dinosaur family tree

Researchers proposes radical overhaul of dinosaurs’ family tree

Proposing a radical overhaul of the dinosaurs’ family tree, a team of researchers said that the meat-eating group of the extinct creatures that includes Tyrannosaurus rex shouldn’t be placed with the long-necked, four-legged plant-eaters like Brontosaurus.

The newly-proposed dinosaur family tree includes two reformulated categories (clades) of the extinct creatures to replace the two that have been recognized since 1888.

Strange insect prompts scientists to create new scientific order

Strange insect prompts scientists to create new scientific order

A new scientific order has been created for a recently-discovered insect that lived in a region what is now known as Burma nearly 100 million years ago, alongside dinosaurs.

According to a new study published in the journal Cretaceous Research, the tiny insect with an “alien-like” appearance and unusual features was discovered by Oregon State University (OSU) researchers in amber.

The researchers described the ancient fossilized creature as a small, wingless female insect that lived in fissures in trees’ bark. It might have fed on worms, mites or fungi.

Researchers discover ‘alien-looking’ insect trapped in amber

Researchers discover ‘alien-looking’ insect trapped in amber

A recently discovered alien-looking fossilized insect is so strange that it not only required to be named as a new species, but also to be placed under a new scientific order, researchers reported.

The alien-looking tiny insect with a strange head and long skinny legs crawled around on trees in a region what is now known as Burma nearly 100 million years ago, in the time of the huge dinosaurs.

Some dinosaur eggs took 6 months or even more to hatch: study

4A---Some dinosaur eggs took 6 months or even more to hatch: study

Eggs of duck-billed dinosaurs took as long as six months to hatch, while the eggs of larger dinosaurs might have taken even longer time to hatch, a new study suggested.

A team of researchers led by Gregory M. Erickson of Florida State University used a new technique on some rare fossils of unhatched dinosaur embryos, and determined that those embryos consumed twice as long to hatch as bird eggs of similar size.

‘Lucy’ had strong climbing arms: Research

‘Lucy’ had strong climbing arms: researchers discover

A new study has suggested that “Lucy,” a more than 3 million year old human relative at the evolutionary cusp between humans and primates, would climb trees regularly and she spent a lot of time in treetops.

Lucy was able to walk upright on two legs, like moderns humans. But, scientists were previously unable determine whether she climbed trees regularly like nonhuman primates or not.

Pre-human “Lucy” climbed trees: Study

Pre-human “Lucy” climbed trees: study

The pre-human “Lucy” either lived in trees or at least spent a lot of time in trees, a new analysis of the little hominid’s skeleton suggested.

A tem of researchers from that Johns Hopkins University and University of Texas conducted scans of Lucy’s skeleton, a more than three million years old fossil that is also known as AL 288-1. Bone scans showed that Lucy’s upper arms had been thicker and stronger than her thigh bones. The same pattern is found in chimpanzees.

Nature can incorporate silicon into building blocks of life: study

4A---Nature can incorporate silicon into building blocks of life: study

A new study has suggested that nature can incorporate silicon into the building blocks of life, which can potentially make it feasible for life to form from silicon and not from carbon as humans did.

A team of researchers led by Jennifer Kan of the California Institute of Technology (Caltech) used a bacterium to produce a silicon-carbon bond naturally. Previously, it was only done synthetically.

Restoration team uncovers hidden layers of Jesus’ tomb site

Restoration team uncovers hidden layers of Jesus’ tomb site

For the first time in centuries, a restoration team has exposed the original rock surface where Jesus Christ is believed to have been buried in Jerusalem.

The restoration team, including experts from the National Technical University of Athens in Greece, peeled away a marble layer in the innermost chamber of a tomb at the Church of the Holy Sepulchre to reach the original rock surface.

Researchers examine first-ever dinosaur brain tissue

Researchers examine first-ever dinosaur brain tissue

The first time discovery of a fossilized brain tissue from a dinosaur is expected to shed more light on the extinct species that lived during the early Cretaceous period, paleontologists believe.

The brain tissue in question, which looked like an unassuming brown pebble, was unearthed by a fossil hunter named Jamie Hiscocks in Sussex, England, more than ten years ago.

Fish Fossil Offers More Information on Evolution of Animal Jaws: Research

Fish Fossil Offers More Information on Evolution of Animal Jaws: Research

After analyzing 423 million year old fish fossils, researchers from Sweden and China have offered interesting information about evolution of animal jaws. The research team analyzed fish fossils found in China's Yunnan province belonging to Qilinyu rostrata fish species. The study results have been published in journal Science.
