Jackals from Halo, anyone?
that dino looks quite ugly.
Awww! So cute!!!
I don't know what to make of this post.
Could be my ex-wife
Starts account at internet forum and posts vaguely related albeit semihumerous responses to a dinosaur thread as his first few posts....
Odd strategy. We will see if it is going to work in his favor.
Scientists find oldest dinosaur
Another strange creature ...

So this creature is from the Triassic Period. Much earlier than anyone expected, 243 million years ago.
Scientists have discovered and described a new supermassive dinosaur species with the most complete skeleton ever found of its type. At 85 feet long and weighing about 65 tons in life, Dreadnoughtus schrani is the largest land animal for which a body mass can be accurately calculated. Its skeleton is exceptionally complete, with >70% of the bones, excluding the head, represented.
I want to see the life size replica.
I ran across an interesting article about the Dreadnoughtus for anyone interested
^ nice article thanks
Another bunch of weird newly discovered dinosaurs
Paleontologists have discovered a new genus and species of ankylosaur that roamed what is now the Gobi Desert in Mongolia during the Upper Cretaceous, between 100.5 and 66 million years ago.
I'm starting to think that these are the same old dinosaurs, but just in broken pieces and thus they call them 'new'
Btw, any transitional fossils yet?
How can they figure out the spines? Were they present with the skeleton structure or ca they see it from bone structure? Similarly confusing was the debate about velociraptors being like lizards or like feathered birds. I thought feathers would leave an imprint in the rock structure around the deceased dinosaur.
The velociraptor has long been depicted as a scaly creature. That's all changing as fossil evidence shows how widespread feathers were among dinosaurs.

The Yutyrannus, described in 2012, are the largest known dinosaurs with feathers — a patch of fossilized skin shows shaggy body feathers, similar to an Emu. Yutyrannus was related to T. rex and measured 30 feet long and weighed > 3000 pounds. Illustration by Maija Karala
I don't really wanna copy-paste, full article can be found here, it's called:

Dinosaurs May Have Danced Like Birds
Lots of speculation about appearance and colors in those videos.
I would have thought they would base it on habitat and environment.
With bright colors usually tropical and neutral colors harsher regions.
170-million-year-old fossilized remains discovered in Patagonia, Argentina, have been identified as a new genus and species of pterosaur.
Pterosaurs were highly successful flying reptiles that lived between 210 million and 65 million years ago. These creatures were Earth's first winged vertebrates, with birds and bats making their appearances much later. They first appeared in the Late Triassic and went on to achieve high levels of morphologic and taxonomic diversity during the Mesozoic era, with more than 150 species recognized so far.
They had an extraordinary adaptation to flight, including pneumatic bones to lighten its weight, and an elongated digit supporting a wing membrane. Some were the largest flying animals of all time, with wingspans exceeding 30 feet.
Another discovered Pterosaur This one is really small:
Paleontologists say they've discovered the fossilized remains of a small-bodied pterosaur, a prehistoric flying reptile, which lived roughly 77 million years ago (Late Cretaceous epoch) and had a wingspan of 5 feet (1.5 m). The new pterosaur belonged to a group of short-winged and toothless pterosaurs called the azhdarchids.
It is unusual as most Late Cretaceous pterosaurs were much larger with wingspans of 13-36 feet (4-11 m).
Previous studies suggest that the Late Cretaceous skies were only occupied by birds and large pterosaurs, but this new finding, which is reported in the journal Open Science, provides important information about the diversity and success of Late Cretaceous pterosaurs.
“This new pterosaur is exciting because it suggests that small pterosaurs were present all the way until the end of the Cretaceous, and weren't outcompeted by birds,” said lead author Elizabeth Martin-Silverstone, from the University of Southampton.
