Inb4 the t rex is agreed to have had long, fleshy, limp whip arms that were far longer than the tiny bones.

They used the long tentacle arms to quickly thwip through the jungle

Oh for sure, without a doubt. Hell it took forever for people to figure out feathers.
Then again, on rare occasion we do get some cool skin/soft tissue evidence like that Nodosaurus in Canada. Sometimes they’re strikingly similar to what we thought (or not?). I am not a paleontologist and I am speaking out of my ass.
That Nodosaurus is super cool though, y’all should see it.

What if there was a dinosaur that literally was just a walking skeleton? 🤔

In October, he was one of nine senators to vote against legislation intended to outlaw flag burning and other forms of flag defacement and joined Bob Dole and Orrin Hatch, the other two Republicans to vote against the bill,
That’s awesome. At least he stood for free speech…
in voicing a preference for a constitutional amendment.

What’s the current consensus, did dinosaurs look more like chickens?
rockerface@lemm.ee 1 year ago
Some definitely had feathers, and some likely were brightly colored
Wiggle_Hard@hilariouschaos.com 1 year ago
In my mind, I picture of Sasquatch riding a dinosaur chicken

From what I know, most raptors had feather and that’s where birds came from.
The broader group of theropods, including the T-Rex, had a precursor to feathers literally called “Dinofuzz”.
All other kinds of dinosaurs I believe are actually scaly like we thought.
TheOctonaut@mander.xyz 1 year ago
This is still not something we can answer with certainty. For a couple of years there, paleontology thought that psittacosaurus had feathers on its tail - and as a ceratopsian, on the complete other side of the dinosaur ‘tree’, that would suggest the base form for dinosaurs must have feathers and any that didn’t have them lost them at some point in their lineage (and thus could potentially regain them if the DNA was deactivated rather than lost). Now the feathers are disputed again, as “something else” - spines of some sort unrelated to feathers.
No doubt lots of dinosaurs were scaly, but I don’t think anyone would say with certainty that feathers were limited to late theropods.
StalinIsMaiWaifu@lemmygrad.ml 1 year ago
Proto-feathers (basically hair) were basal to dinosaurs + pterosaurs, we have evidence for feathers on some dinosaurs (micro raptor had iridescent black feathers), fuzz on others (Psittacosaurus has long “quills” on its backend), and scales on others (Carnotosaurus, Diplodocus, large portion of T-Rex)
The idea right now is that the smaller ones probably had feathers, bigger ones had scales, unless they’re from China, then everything has feathers

Check out Prehistoric Planet, they say they used the latest research to make the dinos, feathers and all

Mammals are different than reptiles. A better comparison would be today’s reptiles.
KillingAndKindess@lemmy.blahaj.zone 1 year ago
Mammals only got yeeted to their own evolutionary tree branch 40 million years prior to those that would be considered reptilian (sorta dinos too) which was somewhere in the realm of 250 million years ago.
Meaninng the reptiles of today are ~5x further apart in time from dinosaurs, than dinosaurs are from their common ancestors to mammals.
I think we really should just not bother thinking in terms of current speciation concepts. They could have had jellyfish like tentacles dangling allover their skin and we’d never know.

As someone who was raised and taught to believe that the earth was only a few thousand years old (by ‘that kind’ of Christians/churches,) this still blows my mind to read! I’ve known what I was taught was bullshit for at least around fifteen years, but it’s like my little pea brain still just cannot compute it. Wild stuff!!

Dinosaurs aren’t reptiles, they’re birds.

All birds are dinosaurs, not all dinosaurs are birds though

Birds aren’t real
1rre@discuss.tchncs.de 1 year ago
And birds and dinos are crocs (unlike most other reptiles)
nBodyProblem@lemmy.world 1 year ago
A better comparison would be today’s birds, which descended from theropods and are the only remaining member of the clade Dinosauria.
