In the News: Elaphrosaur: Rare dinosaur identified in Australia

In May I had quite a few blogs about dinosaurs as I was reading a great book about them. Since then,
I've really been more aware of new findings, and today's blog is about one of those newly discovered! BBC News reported on May 19, 2020- about an Elaphrosaur. To find out what it is, read on.

Elaphrosaur: Rare dinosaur identified in Australia

A fossil unearthed in Australia by a volunteer digger has been identified as a rare, toothless dinosaur that roamed the country 110 million years ago.

The elaphrosaur, whose name means "light-footed lizard", was related to the Tyrannosaurus Rex and Velociraptor.

The five-centimetre (two-inch) vertebrae fossil was discovered during a dig near Cape Otway in Victoria in 2015.

It is the first elaphrosaur bone ever to be found in Australia.

The fossil was discovered by volunteer Jessica Parker, who was taking part in an annual dig led by Melbourne Museum.

At the time, it was thought to be from a flying reptile called a pterosaur. But when palaeontologists at Swinburne University in Melbourne studied the fossil further, they realised it was a delicately-built dinosaur.

"Elaphrosaurs had long necks, stumpy arms with small hands, and relatively lightly-built bodies," Dr Stephen Poropat said.

The fossil indicated the animal was about two metres (6.5ft) long. However, other fossils previously found in Tanzania, China and Argentina show that they could reach up to six metres in length.

Adult elaphrosaurs probably didn't eat much meat, Dr Poropat said.

"As dinosaurs go, they were rather bizarre. The few known skulls of elaphrosaurs show that the youngsters had teeth, but that the adults lost their teeth and replaced them with a horny beak. We don't know if this is true for the [Australian] elaphrosaur yet - but we might find out if we ever discover a skull," he said.

Cape Otway, where the fossil was located, is a rich area for discoveries. About a dozen animals and five dinosaur species have been identified there, according to ABC News. Those discovered include a plant-eating dinosaur found in 2018.

SCIENCE NEWS! Long-necked dinosaur roamed China 160 million years ago

 As a child I (Rob) was fascinated by dinosaurs. I had a small fossil collection, and books on them. I knew every prehistoric period by name and in date order (then!). I had 2-3" plastic dinosaur and prehistoric mammal figures I used to play with. Every year in school I did science reports on dinosaurs.  So, I get excited when a new species is discovered and that happened last week in China. 

Here's the story from EarthSky.org: 

Long-necked dinosaur roamed China 160 million years ago

Scientists report on the discovery in China of a new species of dinosaur – calling Qijianglong – a creature that was “half neck.”

Among dinosaurs, it seems, there were long necks and there were looooonnnnnggggg necks. Paleontologists reported on January 26, 2015 in the Journal of Vertebrate Paleontology on the discovery in China of a new species of dinosaur, a creature that was half neck. They are calling it Qijianglong (pronounced CHI-jyang-lon), meaning dragon of Qijiang, for its discovery in Qijiang, a district of the municipality of Chongqing, China. Construction workers in 2006 stumbled on the fossil site. Scientists ultimately unearthed of series of large neck vertebrae stretched out in the ground – with the head of the dinosaur was still attached. Altogether, scientists say, Qijianglong was about 45 feet (about 14 meters) long. Best estimates suggest it lived about 160 million years ago in the Late Jurassic.
University of Alberta PhD student Tetsuto Miyashita, who was a co-author in the study, was quoted in Science20.com as saying:
Qijianglong is a cool animal. If you imagine a big animal that is half neck, you can see that evolution can do quite extraordinary things.
It is rare to find a head and neck of a long-necked dinosaur together because the head is so small and easily detached after the animal dies.
China is home to the ancient myths of dragons. I wonder if the ancient Chinese stumbled upon a skeleton of a long-necked dinosaur like Qijianglong and pictured that mythical creature.

The Science20.com post also said:
The new species belongs to a group of dinosaurs called mamenchisaurids, known for their extremely long necks sometimes measuring up to half the length of their bodies. Most sauropods, or long-necked dinosaurs, have necks only about one third the length of their bodies.
Unique among mamenchisaurids, Qijianglong had neck vertebrae that were filled with air, making their necks relatively lightweight despite their enormous size. Interlocking joints between the vertebrae also indicate a surprisingly stiff neck that was much more mobile bending vertically than sideways, similar to a construction crane.
Mamenchisaurids are only found in Asia, but the discovery of Qijianglong reveals that there could be as many differences among mamenchisaurids as there are between long-necked dinosaurs from different continents.
The Qijianglong skeleton is now housed in a local museum in Qijiang.
Bottom line: Scientists reported last week (January 26, 2015) on the discovery of a new species of dinosaur called Qijianglong. It’s one of the group of dinosaurs called mamenchisaurids, whose necks sometimes measure up to half the length of their bodies. It was unearthed in Qijiang, a district of the municipality of Chongqing, China, where many other dinosaur fossils have been found.
