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.

New Dinosaur Species Discovered in Australia after Fossilized Bones Found in Queensland

New Dinosaur Species Discovered in Australia after Fossilized Bones Found in Queensland

Scientists have hinted about finding a new species of dinosaurs after they analyzed fossilized bones found by Queensland resident David Ellioitt. The massive bones have led scientists to suggest new family tree for sauropods which could have thrived in Australia during the past. Mr. Ellioitt now heads Australian Age of Dinosaurs Museum in Australia. The analysis suggests that dinosaur could be 40-50 feet long.

Evolutionary history of dogs seem to include Bear dogs
Fragmentary fossilized carnivore remains that sat largely unnoticed in a drawer at Chicago's Field Museum after being unearthed in southwestern Texas nearly three decades ago belonged to a strange group of extinct species known as "bear dogs."

Drepanosaurus fossil defies convention on how reptiles evolved and flourished

Drepanosaurus fossil defies convention on how reptiles evolved and flourished

Newly discovered fossils of a 200-million-year-old reptile are changing the common perceptions on how reptiles evolved and flourished. The Current Biology-published paper has unveiled that Drepanosaurus, which was found in a New Mexico quarry, was the size of a cat and lived in the trees.
