Are Dinosaurs more Lizard/Reptile or are they more like a bird?

i was just inspired by this quote!

check out these pix of some dinosaurs. we have always associated Dinosaurs as big lizards but i've noticed that many resemble birds esp. in the hind-quarters from the thigh down through to the talons.

look at these big guys. it kinda looks like they have big chicken legs.

and even some of the smaller ones have feathers.

what do u think? i would esp. love to hear from our local forum scientists and geneticists.

Seems the latest things I've read show a very close relationship between birds & reptiles, but as to which came first, "the chicken" or the lizard, we've long-
assumed it was the reptiles but it may well have been "birds"? And there were some pretty fierce "birds" flapping around back then...:O

I'm no scientist, but I'm gonna say that certain dinosaurs, like the winged varieties and the bipedal types, are definitely more bird like. Others, your four legged ground pounding varieties, clearly evolved into today's reptiles. I mean, seriously, look at a komodo dragon. It pretty much still is a dinosaur.

There is very clear evidence that most known dinosaurs that people imagine are direct descendants of today's modern birds. Scientists are finding more and more fossils of feathers on these dinosaurs, so most of the dinosaurs pictured here would have actually been feathered.

I gotta say dinosaurs are definitely more like birds, I have a macaw and I call him a T-Rex. He looks like a T-Rex and bites really really hard like a T-Rex would. :P

Ever seen a Muscovy duck that's a bit past the down stage going for a bug? A killer dinosaur if I ever saw one. :)

I believe a bit of both. Alligators are virtually unchanged from their ancient ancestors, but there are a number with bird-like qualities.

Majority of the bipedal carnivorous, raptors, rex etc, dinosaurs are thought to be most related to birds. I believe the Archaeopteryx was the first or one of the first dinosaurs discovered with feathers.
There were also several aquatic dinosaurs, like the mosasaurs or plesiosaur, that were closer to being lizards as well as many quadrupedal land dinos [emoji4]

I voted for eating a dinosaur because that sounds cool, but I agree that they are more like birds! I totally believe that many dinosaurs had feathers.

As someone who has had pet chickens, I have to say that I've always felt chickens look very "dinosaur-like" especially before they are fully grown. Something about the head shape in particular.

And then there's the cassowary bird, which might as well be a living dinosaur:

One thing I also wonder about is whether dinosaurs really had slitted eyes like they do in most drawings, which makes them look more reptilian. Only nocturnal snakes have slitted eyes though, so if dinosaurs were diurnal wouldn't that mean they have round eyes like a chicken or a corn snake?

Ever seen a roadrunner or a heron move, hunt, or eat? Better than watching Jurassic Park.

Man, now I want to eat a dinosaur. :P

Here is a picture of my blue and gold T-Rex (macaw) Jacob, he is eating his favorite, beef, like a T-Rex probably would. I know macaws aren't supposed to eat meat but he loves it so much so I give him a little piece once in a while. I've always called him a T-Rex as he bites really hard and also looks like one. He has his T-Rex moments where he tosses his toys around like a psycho and I always tell him to stop being such a T-Rex. lol

Here are some pictures I drew depicting what Jacob would look like back in the day as a dinosaur. These look more like raptors but I guess so does he, I just call him a T-Rex because of how scary he can be and how hard he chomps.

These are just drawings and aren't of any real dinosaurs but it was fun portraying my macaw as dinosaurs. :)

I actually read paleontological articles and books in my spare time so here's the common consensus among most scientists today:

Birds are dinosaurs. They evolved from a few specific lines of theropod dinosaurs (most likely the Dromaeosaurs which are your typical 'raptors, etc). By the time the meteor hit, there were already birds in the sky and they had already diverged from their dinosaur brethren. The reason they weren't taken out is the same reason we are around: our tiny mammalian ancestors were too small. We were able to burrow and hide in places that the monsters of the time weren't. They were also opportunistic - they could probably eat a mixtures of plants, seeds, and meat, which allowed them to survive after the big boom.

Reptiles such as turtles, crocs, lizards, etc all evolved completely separately from the dinosaurs and can typically be traced to FAR older biological timelines. They also survived the big crash most likely due to size, diet, etc.



Here's a really great book for those that are interested in this sort of thing (and I promise it's not boring - the author is a contemporary paleontologist, and he tells his story with a lot of fun): The Rise and Fall of the Dinosaurs by Steve Brusatte

There has been a lot of research showing that birds are very closely related to dinosaurs. Their feathers are basically modified scales. They have hollow bones just like dinosaurs. Anatomy is very similar. There have been recent discoveries of some "transitional" creatures that are dinosaurs with feathers. All very fascinating. I was lucky enough to see Sue the famous T. Rex at Chicago's Field Museum a few months ago and I could totally see it.

And, after working closely with my daughter's chicken this year, I can totally see them as tiny dinosaurs. (but we don't eat chicken or other meat so lucky for her!)

Just watch a chicken run around all excited chasing after some bug in the yard. Same effect! :rofl:

It's nice to speculate but without a time machine we will never know.
