How did sauropods reproduce?
All dinosaurs reproduced by laying eggs, just as living birds and many modern reptiles do. But surprisingly, the babies that hatched out of sauropod eggs were generally no bigger than a modern adult goose. Sauropods didn’t start out extremely big—they just grew very, very fast.
Are Argentinosaurus plant eaters?
DIET: Argentinosaurus was a long-necked plant eater, which feasted primarily on conifers.
How Do dinosaurs reproduce?
Dinosaurs must have had sex to reproduce. As in nearly all modern-day reptiles, males would have deposited sperm inside females, which would later lay fertilized eggs containing developing dinosaur embryos.
Why did the Argentinosaurus go extinct?
The mass extinction, caused by an asteroid that hit Mexico, doomed most creatures but some bird-like dinosaurs survived.
Did oxygen make dinosaurs bigger?
For a long time, researchers theorized that high oxygen contents in the atmosphere could have allowed dinosaurs to grow to larger sizes, much like arthropods like Meganeura did in the Carboniferous.
What dinosaur laid the biggest eggs?
Dinosaur eggs vary greatly in size and shape, but even the largest dinosaur eggs (Megaloolithus) are smaller than the largest known bird eggs, which were laid by the extinct elephant bird. Dinosaur eggs range in shape from spherical to highly elongated (some specimens three times longer than they are wide).
Which dinosaur is vegetarian?

What is the largest herbivore ever?
Summary: When is an elephant a picky eater? A study of the African elephant finds that, despite its large size and fast-operating digestive system, this mammal does not eat just anything.
Can dinosaur DNA be extracted from mosquitoes?
While this might seem possible at first glance, it’s highly unlikely that scientists could find usable dinosaur DNA in mosquito fossils. Scientists would need a very specific specimen — a female mosquito that had consumed lots of dinosaur blood immediately before landing in tree resin.
Could a dinosaur breathe today?
Yes. Given the recent studies as described here and here show that oxygen levels were actually lower (10 to 15% as compared to 21% today). So breathing would be the least of dinosaurs problem. Dinosaurs might then be subject to oxygen toxicity effects, which can be lethal.
Can humans breathe same air as dinosaurs?
However, you might be breathing some of the same air that dinosaurs breathed millions of years ago. Today, it takes about 6 million years for an O2 molecule to be made by photosynthesis and then to react with other elements to be taken out of the air.
What is the strongest herbivore dinosaur?
1. Triceratops (†Triceratops horridus)
| Kingdom | Order | Genus |
|---|---|---|

What is the 2nd biggest dinosaur?
