What was it like in the Mesozoic Era?
Earth’s climate during the Mesozoic Era was generally warm, and there was less difference in temperature between equatorial and polar latitudes than there is today. The Mesozoic was a time of geologic and biological transition. During this era the continents began to move into their present-day configurations.
What makes the Mesozoic Era unique?
The Mesozoic Era was the time from 248 million to 65 million years ago. During the Mesozoic, the Earth was very different than it is now. The climate was warmer, the seasons were very mild, the sea level was higher, and there was no polar ice.
What was the plant life like in the Triassic period?
The dominant understory plants in the Triassic were the ferns, while most middle-story plants were gymnosperms (plants having exposed seeds)—the cycadeoids (an extinct order) and the still-extant cycads and ginkgoes.
Is Apatosaurus real?
Apatosaurus lived about 152 to 151 million years ago (mya), during the late Kimmeridgian to early Tithonian age, and are now known from fossils in the Morrison Formation of modern-day Colorado, Oklahoma, New Mexico, Wyoming, and Utah in the United States.
What type of plants existed in the Triassic period?
What was life like during the Mesozoic era?
The Mesozoic Era began roughly around the time of the end-Permian extinction, which wiped out 96 percent of marine life and 70 percent of all terrestrial species on the planet. Life slowly rebounded, eventually giving way to a flourishing diversity of animals, from massive lizards to monstrous dinosaurs.
What kind of animals died in the Mesozoic era?
The Mesozoic closed with an extinction event that devastated many forms of life. In the oceans all the ammonites, reef-building rudist bivalves, and marine reptiles died off, as did 90 percent of the coccolithophores (single-celled plantlike plankton) and foraminifera (single-celled animal-like plankton).
What did the Mesozoic era mean for dinosaurs?
Mesozoic. Mesozoic (252-66 million years ago) means ‘middle life’ and this is the time of the dinosaurs. This era includes the Triassic, Jurassic, and Cretaceous Periods, names that may be familiar to you. It ended with a massive meteorite impact that caused a mass extinction, wiping out the dinosaurs and up to 80% of life on Earth.
What kind of plants were in the Mesozoic era?
Terrestrial vegetation was still dominated by ferns, cycads, gingkos, and conifers – all gymnosperms. Insect herbivores, especially beetles, diversified during this time to feed on the abundant vegetation. Modern Gingko biloba leaf. An ancient species, this tree is used extensively in urban plantings.
