Horse-Sized Dinosaur Fossil Sheds Light on the Evolution of T. Rex

Tyrannosaurs were one of the most fearsome predators ever lived on Earth. But how T. rex transformed from small body species to giant carnivores has been a long mystery because of limited availability of fossil record.

Now, researchers have discovered a species of tyrannosaurs in central Asia which lived about 90 million years ago, almost the same time when T. rex started to get bigger. Though new species was not the ancestors of T. rex but fills the 20 million year gap in the fossil record of tyrannosaurs.

The skull of newly discovered dinosaur species looked similar to that of T. rex but its brain and senses were already highly developed, It indicates that tyrannosaurs had to get smart before they got big and the transition and growth in size occurred suddenly towards the long end of the long evolutionary history of the iconic predator. 

Mysterious Fairy Circles Also Found in Australia

Bizarre bald patches of land were first discovered in Africa decades ago but recently similar kind of patches, also known as fairy circles, have been spotted in Australian outback too. The mysterious circles are evenly spaced and covering a widespread landscape in a hexagonal pattern.

These circles have baffled researchers for many years and various explanations have been associated with them. But when researchers studied the recently discovered fairy circles both on the ground and from the air, they found that these circles are formed due to cutthroat competition for water among plants where dominant plants pull more water from the soil than weaker plants. Lack of water devastates less dominant plants and leaves barren land behind.

Mystery of Tully Monster Finally Solved

For almost six decades, paleontologists have puzzled over the Tully monster’s identity and its place on the tree of life. But now they believe they have finally solved the mystery of the sea creature which has sharp needle-teeth and eyes perched at the either side of a long, rigid bar. Researchers claim that Tully monster is a vertebrate indeed because it had a rudimentary spinal cord. 

The fossil of Tully monster was discovered in 1958 inside 300 million years old rock. The bizarre creature was a mixture of unique characteristics and body parts and was so strange that even scientists were unable to fit into any major animal group and gave it the name ‘monster.’

Hubble Spots a Cluster of ‘Monster Stars’

Hubble Space Telescope has spotted a cluster of nine gigantic stars – each one more than 100 times massive than the Sun. The young star cluster R136 is the largest sample of most massive stars identified to date. 

The stars are not extremely massive but extremely bright as well. Together they can outshine Sun by a factor of 30 million. One of the stars in the cluster is R136a1, which is the most massive known star in the universe.

Bright Spots on Ceres are Changing

Bright spots on dwarf planet Ceres are more complicated than originally thought.

A team of researchers have recently detected the motion of spots due to the rotation of Ceres about its axis and also observed unexpected changes in those spots. Researchers found that bright spots on Ceres’ crater Occator are fluctuating in a way that had not been predicted. They are evaporating in sunlight and freezing at night, indicating Ceres is much more volatile and geologically active world than anyone expected.

Ceres is the largest body in the asteroid belt between Mars and Jupiter. The most prominent feature of the dwarf planet is its bright spots, which have been detected last year when Dawn spacecraft entered the orbit of Ceres.
