The modern-day mammal, specifically the placental mammals, did not live during the time of the dinosaurs. While some early mammals existed during the Mesozoic Era, they were small and not the diverse group we see today. The major diversification of placental mammals occurred after the dinosaurs went extinct around 66 million years ago. Thus, many of the mammals we are familiar with today emerged long after the age of dinosaurs had ended.
Yes, all dinosaurs are extinct. But, their modern-day ancestors, reptiles and birds, live on.
No, dinosaurs existed during the Mesozoic era, which ended about 66 million years ago. The Cenozoic era began after the Mesozoic era and continues to the present day, during which mammals became the dominant land animals.
Herbivorous dinosaurs probably spent most of the day and even night foraging. Some of them probably lived in herds.
Dinosaurs as most people think of them are completely extinct. However, birds evolved from dinosaurs, and as such, are considered to be a group of dinosaurs. Since birds are still alive today, so are some dinosaurs. No dinosaurs other than birds are alive today, though.
All foxes live during the day.
the herbivores
The first dinosaurs are believed to have emerged during the late Triassic period, around 230 million years ago. Among the earliest known dinosaurs is Eoraptor, a small, bipedal herbivore or omnivore found in present-day Argentina. Other contenders include Herrerasaurus, which was larger and more carnivorous. These early dinosaurs marked the beginning of a diverse lineage that would dominate the Earth for millions of years.

No
The dinosaurs existed as they evolved best to fit the ecological niches of the day.
None-avian dinosaurs first appeared in the Triassic period and were the dominant land vertebrates through the Jurassic and Cretaceous periods. At the end of the Cretaceous period, 65.5 million years ago, all non-avian dinosaurs went extinct. Birds, which are now classified as dinosaurs, continue to live to his day.
