dinosaurs, how the hel do they know how they fed on prey other than stomach contents?

[Rusty420]

Title question TD crew, watching a CGI dinomentry and wondering how they know that the little one took chunks out the big herbivore, and chows down on the chunk, then continues to chase and take chunks out of it...wtf technology or bone remains lets the scientist know how these prehistoric fuckers played with they food, didnt have fur, smoke weed, and build pyramids wiith musical instruments?

 

[TrichyTrichy]

some were scavengers so no tasty innards for them.
great question

I actually just watched a BBC docu that explained a lot of this.

Extinct: A Horizon Guide to Dinosaurs
Dallas Campbell delves in to the Horizon archive to discover how our ideas about dinosaurs have changed over the past 40 years. From realising that lumbering swamp dwellers were really agile warm blooded killers, astonishing new finds, controversial theories and breakthrough technology have enabled scientists to rethink how they lived and solve the mystery of their disappearance. And they can even reveal whether dinosaurs might still be with us today.

thanks, maybe they make it up for the program to explain fossilised remains, employ writers etc....besides, sittin here i cant think of a way to prove the existance of organic products in the majority of remains, being made of bones n shit, i mean frozen mammoths etc, yeah, but this shit..???

Sorry dude, missed you there. thats cool, i will look it up, dude musta written a book to get a tv show, and books a cheap naw days as peeps dont read paper much..

P.s. i dont normaly watch tv, the Ganjihad i was on has stopped for outdoor season so im catching up on couch time...

type of teeth prob

 

[Rusty420]

nah dude, thats basic what did they eat, meat or veg or both shit..cavities etc show that they invented candy before we did..

 

[MMJcali]

yes. dinosaurs invented music; and many scientists are now speculating that velociraptor youth regularly attended raves.

its all in the bones

god damn it wtf are you smoking i want me some

 

[WelderDan]

A lot about what something eats can be inferred from tooth shape. Also, fossilized remains have been found with broken/shed teeth of the dino's that ate them. Tooth marks in bones have been matched to skulls. We know T-Rex hunted live prey from tooth marks in bone that have healed. We also know what dino's ate based on coprolite (fossilized crap) evidence.

I watch a lot of Discovery/History/Science channel.

 

[Sour Deez]

All i know is i was a little upset to find out the Velociraptor is no taller then a turkey and is covered in feathers.

Jurassic Park fooled me.

And there are dinos still around today... crocodiles

T rex closest living relative is the bird.

 

[HempHut]

Most of the behaviour stuff are just guesses. No real idea if certain species hunted in packs, alone, etc. I saw a fairly strong argument that T-Rex might have actually been a scavenger -- more like a vulture than a hunter.

Same with skin colour and coverings. More evidence suggesting they were feathered much more frequently than we thought, etc. Colour and skin are mostly just guesses based on current creatures. They might have been bright pink for all we know.

 

[TrichyTrichy]

the allosaurus hunted in packs but a lot of other small and large ones did as well. similar how 'resident and transient' whales do today.

You may have seen the same documentary I checked out a couple years ago, can't recall the title nor the paleontologist's name.

Anyway, this guy talks about the idea of T-Rex being an apex predator. For several hundred years we thought a big ass bipedal meat eater was chasing down large critters and that's how they got so big.

The paleontologist says conventional wisdom is wrong, T-Rex couldn't tangle with live prey because of it's substantially underdeveloped arms. Therefore, T-Rex appears to be an apex scavenger and was compared to a turkey vulture.

This guy also reinforced the scientific opinion that dinosaurs were birds. Jurassic Park completed the sequence with frog dna so we know Steven Spielberg is full a shit.

Another clue that T-Rex was a scavenger - no evidence of hunting in packs. Hunting alone could be suicidal. Poor feller's brain wasn't as big as a walnut but even he knew dead stuff was safer than the alternative.

the teeth, the shape of the skeleton. but mostly the teeth.

(pretty convincing its a predator when you find bitemarks in another skeleton that match the teeth of this skeleton, and then to boot, the one bit is a lumbering, obviously slow creature and the biter sleek with a powerful quick build)

plus teeth for eating greens are totally different from the teeth of predators. (and scavenger teeth are distinct from both, omnivores as well have different teeth)
now there are exceptions, but this is generally so.

my question is what were the feathers for???? What purpose did they serve???????

My understanding (albeit most likely wrong) was that birds evolved from dinosaurs...but...maybe some birds evolved into dinosaurs?????? Meaning there were birds before dinosaurs???? Strange stuff.

But if a velicoraptor has feathers...I would think that they either developed feathers for some reason...or they were descended from birds, and the feathers are just a throwback...like the canine teeth in humans...they've recessed under the gums, but they're still huge...and we used them to tear meat or fight each other.

So I guess I want to know what came first...the dinosaur or the feather

 

[wisco61]

What were dinosaur feathers for?

The study of these simple, fossilised dinosaur feathers soon made it clear that they were not used for flight, as they are not of the assymetrical shape required to generate lift. So it is safe to presume that their key functions were either as a means of insulating the body (or perhaps shielding their young from excessive heat), and/or a means of display to attract mates or to warn off predators. Another theory is that they may also have played a role in helping tree-dwelling theropods such as Microraptor to glide from one tree to another.

the first dinosaurs with feathers was the lesbian female dinosaur: Lickalotpus

(when your mouth is dry...you're plenty high)...

 

[Rusty420]

thats stupid H2O, the feathers were for making they pillows...and duvet covers....i also heard that the herbivores composted the feathers they found and grew weed with it...
