Evidence for group behavior among dinosaurs includes fossil findings of trackways showing multiple individuals moving together, suggesting herding behavior. Additionally, mass death sites, where numerous individuals of the same species are found together, indicate social interactions. Some fossils also reveal nesting sites with multiple nests in proximity, implying parental care and communal breeding. These findings collectively suggest that many dinosaur species engaged in social behaviors similar to those observed in modern animals.
Yes. Herrerasaurians were among the very first dinosaurs.
Climate change is among the theories proposed to explain the extinction of the dinosaurs. Evidence includes fluctuations in global temperatures, changes in ocean chemistry, and the release of greenhouse gases. Fossil records also show a rapid decline in biodiversity around the time of the dinosaur extinction event.
Dinosaurs weren't intelligent enough to segregate eachother.
Behavior among men and women would be more universal around the world.

Smaller dinosaurs such as a compsognathus would eat insects and small mammals. Carnivorous dinosaurs would go for herbivores or sometimes resort to cannibilism among their own kind.
Yes, dogs can masturbate, and it is a relatively common behavior among them.
Scientists use molecular evidence, such as DNA and protein sequences, to assess genetic similarities and differences among organisms. Fossil evidence provides insights into the historical progression and transitional forms of species. Morphological evidence examines physical traits and structures to identify commonalities and differences. Lastly, behavioral evidence looks at patterns of behavior that may indicate evolutionary relationships based on shared ancestry.
Triceratops, Tyrannosaurus, and Alamosaurus were three of the dinosaurs that existed 65.5 million years ago. They were among the last dinosaurs, and died out as a result of the asteroid impact at Chixculub.
All dinosaurs, including birds, which are considered a group within the clade Dinosauria, laid eggs.It is unknown whether dinosaurs were warm blooded or cold blooded. Possibilities include:All dinosaurs were warm blooded, and none were cold bloodedAll dinosaurs were "lukewarm" blooded, meaning they had some control over their body temperatures, but not as much as modern warm blooded animals, like mammals or birds.All dinosaurs were cold blooded.Some types of dinosaurs were warm blooded while others were lukewarm or cold blooded.The growth rate of dinosaurs as revealed by their fossilized bones and the fact that their anatomies suggest very active lifestyles, which cold blooded animals would not be able to maintain, among other pieces of evidence, strongly suggest that at least theropods were warm blooded, if not all dinosaurs. Theropods were three toed, bipedal dinosaurs, most of which ate meat. Examples includes T-rex, Velociraptor, Allosaurus, Troodon, and Ornithomimus.In other words, it appears most likely that all dinosaurs laid eggs, but they were warm blooded.
So far, Herrerasaurus is among the earliest known Dinosaur
