Why didn't mammals evolve more during the mesozoic period?
Mammals did not evolve significantly during the Mesozoic period primarily due to the dominance of dinosaurs, which occupied many ecological niches and limited opportunities for mammals to diversify. Additionally, early mammals were small, nocturnal creatures that may have been outcompeted by larger reptiles for resources. The Mesozoic environment favored the reptiles' adaptations for larger size and varied diets, leading to a relatively slow evolutionary pace for mammals until the mass extinction event at the end of the Cretaceous, which allowed mammals to diversify and thrive.
Is a sloth a dinosaur?
No, they came later. During the last two periods of the Mesozoic (Jurassic and Cretaceous) all the mammals were small and primitive, as the dinosaurs held all the important positions (called "niches"). When the dinos shuffled off, the mammals began to expand in size and complexity to fill the vacancies.
How did reptiles small size help mammals of the mesozoic era?
The hollow bones and feathers of birds made them better adapted to their environment than the flying reptiles which became extinct during the Cretaceous Period. Sources: My science book and my own knowledge
What does mammal mean in size?
Nothing. Mammals can be as small as a mouse or large as a whale.
Do all mammals have a common ancestor?
Not actually. There were several different marine reptiles that had mammalian characteristics, notably the group known as pelycosaurs. The earliest mammals appeared early in the Age of Reptiles (Mesozoic Era), but were uniformly small in size. The group called synapsids took an evolutionary path to mammals while the sauropsids became today's reptiles and birds.
What is meaning of Small Mammals?
Small mammals refer to a diverse group of animals that are relatively small in size and have fur or hair. This category includes rodents, shrews, rabbits, and some small carnivores like weasels and martens. Small mammals play important roles in various ecosystems as prey for larger animals, seed dispersers, and ecosystem engineers.
What do snakes do for food?

Do mermaids go to the restroom?
just like other mammals do. There is a small hole at the bottom of their tail. The size of a small pebble. They go like a fish.
Is a praying mantis a pest or helpful?
actually helpful, imagine one of these things the size of even a small crane, though, some science fiction writers have!
What is the length of a kangaroo's small intestine?
The length of a kangaroo's small intestine is moderate in length compared to other mammals the length varies depends on the size of the kangaroo.
