New Ancient Shark Species Discovered in Alabama

  New Ancient Shark Species Discovered in Alabama 80-million-year-old teeth rewrite what we know about shark evolution.Now, scientists have discovered a dinosaur-era shark may have been an even earlier ancestor of megalodon, illustrating the evolution of one of the most fearsome creatures to swim the earth.

More than 10 years after finding foot and tail fossils in Victoria's south-west, scientists have identified a new dinosaur that roamed what has been described as Australia's "lost world".

The fossils were found in 113-million-year-old rocks that form a sea platform near Cape Otway in 2005 by a volunteer prospector.

University of Queensland's School of Biological Sciences alumnus Dr Matt Herne said scientists have now figured out the bones belonged to a turkey-sized herbivore, which lived in the Australian-Antarctic rift valley.

Chinese 'rainbow dinosaur' had iridescent feathers like hummingbirds

  Chinese 'rainbow dinosaur' had iridescent feathers like hummingbirds Scientists on Monday announced the discovery of a crow-sized, bird-like dinosaur with colorful feathers from northeastern China that lived 161 million years ago during the Jurassic Period. They named it Caihong, the Mandarin word for rainbow. Microscopic structures in the exquisitely preserved, nearly complete fossil unearthed in Hebei Province indicated that it boasted iridescent feathers, particularly on its head, neck and chest, with colors that shimmered and shifted in the light, like those of hummingbirds.

More than ten years after finding foot and tail fossils in Victoria's south west, scientists have identified a new dinosaur that roamed what has been described as Australia's "lost world". The fossils were found in 113-million-year-old rocks that form a sea platform near Cape Otway in 2005

"It's taken quite a while to … work out exactly what the skeleton is, and what the skeleton's evolutionary relationships are," he said.

"It takes time and very careful and detailed examination, so that's partly why it's taken so long to get out to now."

The dinosaur has been named Diluvicursor pickeringi, meaning Pickering's flood-running dinosaur, after the late David Pickering, who was Museums Victoria's collection manager for vertebrate palaeontology.

Dr Herne said it took a team of people doing field trips to work out what the dinosaur was like and the kind of environment it lived in.

"From what we can tell, even though it's only preserved a tail and a foot, from those bones, we can talk from similarly related things, that it was a biped, so it ran around on its two strong hind legs," he said.

This particular dinosaur probably weighed between 3 or 4 kilograms, but its species have grown to a size of 2.3 metres in length, and up to 17kg.

Unlike the turkey, it was probably scaled, rather than feathered, with a beak and grinding teeth for eating vegetation.

The team's research also involved a detailed analysis of what the Australian-Antarctic rift would have been like when it was inhabited by dinosaurs.

"The environment that the lived in is really exciting, because it was in fact a big rift valley that existed between Australia and Antarctica," Dr Herne said.

"And on the eastern margin of it was a massive volcanic mountain range, possibly akin to the Andes, and of course this all gone now.

"So what we're looking at is a lost world, basically Australia's lost world … the only rocks that we can actually visit and look at this lost world are on the south coast of Victoria."

UN Security Council refrains from condemning Turkey .
The UN Security Council discussed Turkey's intensifying offensive against Kurdish militias and the worsening humanitarian crisis in Syria on Monday but did not condemn or demand an end to the sensitive Turkish operation. Already scheduled to hear a report from UN aid chief Mark Lowcock on his recent visit to Syria, at France's request the Security Council also touched on the latest Turkish offensive as well as the Syrian campaign in Idlib and Eastern Ghouta.
