One thread for all news stories related to dinosaurs and prehistoric beasties! :ahoy:
A species of dinosaur that packed hundreds of teeth inside its giant beak has just been described by scientists. The Gryposaurus, discovered in southern Utah, had a distinct duck-like bill and a powerful, strengthened jaw.
The two-legged creature, described in the Zoological Journal of the Linnean Society, was more than 10m (30ft) long.
The ferocious Velociraptor, made famous in the movie Jurassic Park, was probably covered in feathers. A re-assessment of a fossil forearm unearthed in Mongolia in 1998 has revealed an array of small bumps.
In modern birds, such "quill knobs" are the locations where secondary feathers, the flight or wing feathers, are anchored to the bone with ligaments.
The American Museum of Natural History and the Field Museum of Natural History report their study in Science magazine.
Full story! I take it this is especialy timely, considering the preview pics I've seen for Journey to Chandara?
Birds' dinosaur ancestors were shrinking long before the development of flight, researchers say. In the current Science magazine, they show off a tiny Mongolian creature (Mahakala omnogovae), which came from the same dinosaur grouping that also led to birds. It lived 80 million years ago.
I thought it was pretty neat, and kinda cute ... then I realised that it was rendered actual size on my monitor. Tiny!!
A colossal collision in space 160 million years ago set the dinosaurs on the path to extinction, a study claims. An asteroid pile-up sent debris swirling around the Solar System, including a chunk that later smashed into Earth wiping out the great beasts.
Other fragments crashed into the Moon, Venus and Mars, gouging out some of their most dominant impact craters, a US-Czech research team believes.
Its study, based on computer modelling, is reported in the journal Nature.
"We believe there is a direct connection between this break-up event, the asteroid shower it produced and the very large impact that occurred 65 million years ago that is thought to have wiped out the dinosaurs," Dr Bill Bottke from the Southwest Research Institute, Boulder, Colorado, US, told BBC News.
Full story. I find it really interesting because it emphasizes that there is unity, even on such a large scale. Things that affect us here on earth can also have an affect in the rest of our solar system - maybe even in the rest of the universe! It's mind-boggling, and very Dinotopian.
Tyrannosaurus rex would have been able to outrun a footballer, according to computer models used to estimate running speeds of dinosaurs.
The work used data taken directly from dinosaur fossils, rather than referring to previous work on modern animals.
The University of Manchester study published in Proceedings of the Royal Society B, shows T. rex had a top running speed of 8m/s (18mph).
The fastest dinosaur was a small, bipedal and carnivorous species.
This animal, called Compsognathus, was about the size of a chicken, and could run at 18m/s (40mph).
BBC reporter Jacey Normand travelled to the Badlands of Montana, US, in July. She accompanied Manchester palaeontologist Dr Phil Manning in his quest to find a preserved footprint left by the dinosaur T. rex.
To recognise a dino print a good place to start is by examining the bones of the real thing.
The closest most of us ever get to that is via casts, like the one at the University of Manchester's Museum.
Its 3.5m (12ft) T. rex model resides with other bones and information. The beast is like a watchful guardian over the whole collection.
The university's head palaeo-scientist, Dr Phil Manning, points out the enormous size of the animal's feet and explains how, "footprints are just like the shoes which fit the foot".
Victorian dinosaurs in a London park have joined Buckingham Palace as a Grade I listed monument. The Department of Culture, Media and Sport said the sculptures in Crystal Palace Park, south London, are of "exceptional historic interest".
The 15 reptiles were created in the 1850s for the opening of the park when the Great Exhibition was moved there from Hyde Park.
Full story! Arthur Denison would have seen these sculptures, or at the very least known all about them. Neat!
The earliest evidence for the existence of reptiles has been found in Canada. The 315 million-year-old fossilised tracks give an insight into a key milestone in the history of life, when animals left water to live on dry land.
The footprints suggest reptiles evolved between one and three million years earlier than previously thought.
They were found by UK scientist Dr Howard Falcon-Lang in fossil-rich sea cliffs at New Brunswick. "The discovery was pure luck," he said.
Full story! Yay Canadian dinosaur news! ;D The article also contains a photograph with one of our two-dollar coins for size comparison, which I thought was pretty neat. You almost always see American quarters or pennies used for that, so perhaps it would have been better to use a Canadian quarter or penny, as most folks outside Canada don't know how big a twoonie is.
Fossilised body imprints of amphibians have been found in 330-million-year-old Pennsylvanian rocks. "Body impressions like this are wholly unheard of," said New Mexico palaeontologist Spencer Lucas.
Cool! It reminds me of the hollowed-out shapes they found in the ash at Pompeii. Ok, that's creepy.
Giant hyenas, sabretoothed cats, giraffes and zebras lived side by side in Europe 1.8 million years ago.
The creatures' remains were among a vast fossil hoard unearthed at an ancient hyena den in the Granada region of south-east Spain.
The area appears to have been a crossroads where European animals mixed with species from Africa and Asia.
About 4,000 fossils have been found at the unique site. They also include gazelles, wolves, wild boar and lynx.
Full story. I've been to Granada and I'd go back again just to see this!
A 53-million-year-old spider has been revealed in exquisite detail by scientists from the UK and Belgium. The ancient creepy-crawly had been trapped in amber and preserved in a lowland area around Paris, France.
The scientists reconstructed the 1mm creature's original appearance using an X-ray-based medical imaging technique.
The pictures, published in the journal Zootaxa, "digitally dissect" the tiny spider to expose amazing details such as the preservation of internal organs.
"This is definitely the way forward for the study of amber fossils," said David Penney, from Manchester University and lead author on the study.
Full story. Wow! It looks just like a modern spider. The level of detail is absolutely astounding. Speaking of Jurassic Park, eh??
cptstarlight: Dinotopia, like returning to the company of an old friend. Should old friends be forgot and never thought upon? I think not.

bricabrach: And yes! There's nothing like Dinotopia! Breathe deep, seek peace.

DinoAnon: Remember to uphold personal honour and find your own glory in the world and your traditions. Halcyon and the Knights of the Unrivaled could have done no less. Good bye, Dinotopia.

DinoAnon: So to old friends long gone, to times in the past, and with my dearest wishes of positivity in your lives, this is Steven/Lellywin from Canada saying farewell. Breathe deep. Seek peace. Good luck to you all.

DinoAnon: Spending time with Dinotopians. And how much more wonderful and magical the world was.
Nov 8, 2018 23:47:26 GMT -5
DinoAnon: Look at the last Jurassic Park films, still stuck in middle 90's dino science, still such corny nonsense. I think about what we could have had, and it frustrates me, but at the same time I am greatful for the years I spent among Dinotopians...
Nov 8, 2018 23:47:12 GMT -5
DinoAnon: And I have to really wonder how something so special and unique lost its footing in popular culture. There will *never* be anything like Dinotopia, especially as media marches on and continues to provide us such thoughtless and violent garbage.
Nov 8, 2018 23:45:33 GMT -5
DinoAnon: I remember 1995 and the glorious high point of The World Beneath and the exciting world of Dinotopia being explored. I look around now in a decaying fandom, though you don't need a fandom to enjoy something...
