Spinosaurus is First Known Semi-Aquatic Dinosaur
by Jon Tennant
The meat-eating dinosaur Spinosaurus rose to terrifying fame in Jurassic Park III, when it took down the comparatively small Tyrannosaurus rex. Now, thanks to a newly discovered partial skeleton, Spinosaurus has an even greater claim to fame: this fearsome sail-backed beast spent much of its time in the water, a definitive first for dinosaurs.
A global team of paleontologists digitally reconstructed the skeleton of Spinosaurus aegyptiacus based on a new specimen from the Kem Kem beds of eastern Morocco. The fossils confirm that Spinosaurus was more than 49 feet (15 meters) long – at least 8 feet longer than T. rex, in line with previous estimates based on more fragmentary specimens. But the new skeleton was shown to be still growing, so a full adult would have been even bigger.
More unusually, there were signs that the dinosaur was a fantastic swimmer. Researchers determined that Spinosaurus had a suite of adaptations that allowed it to spend much of its time in the water and that, contrary to Jurassic Park’s representation, would have required the animal to walk on all four limbs when it was on land. That makes Spinosaurus the first dinosaur known to be adapted to a semi-aquatic lifestyle…

An instagram user posted the first look at Jurassic World's Velociraptor earlier today, with the attached comment:
This is an actual Velociraptor for the upcoming film Jurassic World! #jurassicworld #dinosaur #universalstudios #StevenSpielberg #Velociraptor #HYPE
The news came from JurassicWorld.org as a rumor, but the site is now stating that multiple sources have confirmed it is legit.
it looks exactly the fucking same but now it’s green
"Ah yes, when people say "make dinosaur look like bird" they must mean "give dinosaur saturated color like bird"."
i think by making it green all of a sudden it’s supposed to make it look more reptilian and act as kind of a huge “f u” to everyone that realises the whole, very evident, completely irrefutable bird/dinosaur relationship
I get the bird/dino relationship thing, but a velociraptor is not a bird. It’s just not. It doesn’t have to be colored like one. If dinosaurs can be considered reptiles, it makes sense that they’d be colored to resemble modern reptiles. But nothing really matters since film is an art and the artists have a little freedom and creativity with making the dinos. Even if we knew exactly what they looked like in real life, the crew should still be able to make them how they want to. Yeah, it’s good to stick to scientific facts, but let’s be real here.
this is one of the most awfully wrong things i’ve ever read i just????? i can barely even make a sensible answer i’m so bewildered
but, no. dromaeosaurs (the clade Velociraptor belongs to) had feathers. they had very extensive feathers. they had such extensive feathering that some of them could fly. dromaeosaurs were just about as close as you could get to a bird without them being an actual chicken, or pigeon, or duck, or Scansoriopteryx, or any sort of bird (bad example i know, but you get the idea, i hope). it was dromaeosaur relatives, like Archaeopteryx, that evolved into what we see as birds today, even though birds are dinosaurs and everything but idk if you know about that so i’ll leave it.
and they may have freedom and creativity but they also have a responsibility to not lie to people omg

This may be speculative.
The theropod lounging on the branch with the platypus is tooooooo much
These are all toooooo much
I am fucking dead.

My life is officially over.
Nothing can ever surpass this.
Just fucking watch it.
“Stella, a four-year-old dinosaur expert, correctly points out that a so-called Triceratops toy is, in fact, a Styracosaurus. She even hits three of the major differences in skull anatomy—Triceratops had a shorter nasal horn, longer brow horns and smaller, triangular bones around the border of the frill”.

expose-the-light: Iridescent Dinosaurs

According to a new study, Microraptors—four-winged, feathered dinosaurs that lived 125 million years ago—sported Earth’s earliest known iridescence, as pictured in this illustration.
The findings are the earliest evidence of iridescence in any creature-bird or dinosaur, said study leader Julia Clarke, a paleontologist at the University of Texas at Austin.
Clarke and colleagues also suggest this iridescent coloring may have helped make Microraptor’s tail feathers even more eye-catching to mates.
Using an electron microscope, the researchers compared tiny, pigment-containing structures called melanosomes in a Microraptor fossil to melanosomes of living birds.
The team found that Microraptor’s melanosomes were narrow, elongated, and organized in a sheetlike orientation—features that produce an iridescent sheen on modern feathers.
“This study gives us an unprecedented glimpse at what this animal looked like when it was alive,” study team member Mark Norell, chair of the American Museum of Natural History’s Division of Paleontology, said in a statement.
The new findings are detailed in this week’s issue of the journalScience.
That top microraptor reconstruction illustration is SOOOO GOOOD :O
