Mammals were small during the Jurassic was because the niches for larger animals were filled by reptiles. Some mammals filled niches as seed eaters. Others were carnivores that ate insects or small vertebrates.
First of all, the carnivorous dinosaurs. Not just dinosaurs, but small, raccoon sized mammals such as cynodonts, and insects. The climate is a setback too. it was rather hot during the Jurassic period in most places too.
A fabrosaurs were small dinosaurs that lived towards the beginning of the Jurassic Period, about 208-200 million years ago.
Jurassic perios the Jurassic period was when the first bird, archaeopteryx, appeared Toward the end of the Jurassic Period, one of the first birds, Archaeopteryx (ahr-kee-AHP-ter-iks), appears. An interesting addendum is that Archaeopteryx is an almost perfect intermediate between the dinosaurs and the birds. It has a series of characteristics that are definitely dinosaurian, yet it has feathers, a wishbone, and wings
Syntarsus was a small, lightly-built dinosaur that weighed between 60 and 70 pounds. It was a carnivore and lived in the Early Jurassic period.
Texas' small mammal is the nine-banded armadillo
Music written during the Classical period for small ensembles is known as chamber music.
It is generally believed that birds evolved from small, feathered, meat eating dinosaur during the Jurassic period. This is because of the similarities between those dinosaurs and early birds, which include feathers, 'hollow' bones (really they have an internal honeycomb structure), beaks, and other similar features. Additionally, animals that appear to be evolutionary links between birds and dinosaurs exist, such as Archaeopteryx.
No, it was based on a fictional book. No, Jurassic Park was a fictional novel by Micheal Crichton that was made into a popular movie. It is not real but the Jurassic time period is real
depends on the mammal But for most small mammals the best trap to use is a mouse trap. ;)
Yes, birds did exist during the Mesozoic. The earliest birds evolved from small, feathered dinosaurs during the late Jurassic, about 150 million years ago.
The earliest period that dinosaurs existed was the Triassic period, some 225 million years ago. These were not the huge dinosaurs of the later period. Most dinosaurs of that age were small creatures that ate meat and walked on hind legs. Shaaron
The Mesozoic era is divided into three periods Triassic, Jurassic and Cretaceous. During the early Triassic, corals appeared. Seed plants dominated the land, in the northern hemisphere, conifers flourished. Glossopteris was the dominant southern hemisphere tree during the Triassic period. Many new dinosaurs appeared during the Jurassic period. Giant plant eating dinosaurs dominated the Earth. carnivores such as Allosaurus and Composognathus were plentiful. Many bird-like dinosaurs also thrived during this period. The Cretaceous period saw the heyday of the dinosaurs. Many new species of dinosaurs evolved during this period. New dinosaurs such as, the deadly t-rex and the extremely large Giganotosaurus appeared for the first time as did Triceratops and many others.
