How might the mass extinction of dinosaurs enable many new species of mammals to develop?

Mammals no longer succumbed to carnivorous dinosaurs as prey and they no longer had to compete with dinosaurs for common food/resources.

Can you describe condition that makes it possible for a species to undergo adaptive radiation?
When the dinosaurs went extinct the mammals that were living alongside the dinosaurs underwent massive adaptive radiation. Large extinction events can give rise to niche openings for species that go through the extinction event.
What is a good question about extinction that you can make up?
Give a reason for the extinction of dinosaurs What species is now in danger of extinction
What effects have mass extinctions had on history life?
Mass extinctions have the effect of eliminating a large number of species, which leaves a wide variety of niches open to new species. Whichever species survive the mass extinction quickly evolve into many new forms to fill the empty niches. The Permian-Triassic Extinction Event left niches open to the dinosaurs, and the Cretaceous-Tertiary Extinction eliminated dinosaurs, leaving niches open to mammals.
What event describes the extinction of all the dinosaurs and about half of the animals and plant species?
crustacious teriary extinction
What event describes the extinction of all the dinosaurs and about half of animal and plant species?
crustacious teriary extinction
What is endangered species and extinction?
Endangered species is when there is a certain type of animal that is losing its population. Extinction is a very old animal that has died out and there is none of them left, e.g dinosaurs.
What is the difference between extinction and species endangerment?
Extinction refers to complete eradication of a species such as the Warrah or Dinosaurs (things that no longer exist), whereas an endangered species is merely under threat of eventual extinction, but is not there yet, like a panda or a California Condor.
Where did the extintion of dinosaurs occurred?
There is no actual place which extinction occurred as dinosaurs are represented on every continent by both extant species and fossil remains.
How mass extinction affected life on Earth?
Mass extinction isn't a natural role in any life-system. They happen as a consequence of some catatrosphic disaster or radical unbalance in the eco-system. As a result of mass extinctions other 'groups' evolve into species that take the place of those exterminated.
What were the dominant species during the Cenozoic era?
There was no one dominant species throughout the Cenozoic, as it was a period of time that stretched from the extinction of the dinosaurs 65 million years ago to the present day, with many changes in climate that would hinder the ability of any one species to be dominant. However, it is perfectly sensible to say that mammals were dominant since the start of the Cenozoic. Mammals at the time of the dinosaurs (the Jurassic and Cretaceous, mostly) were mostly very small scavengers and herbivores. The extraterrestrial impact and flood basalt outpourings that killed the dinosaurs and many other species left mostly animals under 10kg in weight - chief among them the mammals. With no larger predators to kill them, the mammals took the evolutionary opportunity and flourished, leading us to become the dominant species we are today.
Were four legged mammal-like animals that survived the extinction of dinosaurs?
many such as ambulocetes and a species of monkey(look up ambulocetes on Google images).
What was the great extinction?
The most recent one was the Cretaceous-Tertiary event, about 65 million years ago. Prior to it, reptiles were still the dominant species on earth. After it reptiles - especially the huge ones (dinosaurs) gave way to mammals as the dominant species. An event after which the distribution of earth's fauna changed dramatically.
