The Vast Expansive World of Evolved Ants October 18, 2023 Lori Dorn You're Living On An Ant Planet Share Watch on PBS Eons looks at the vast and expansive world that ants have created for themselves through evolutionary advances that took place over millions of years. How did ants take over the world?Jurassic Period, second of three periods of the Mesozoic Era. Extending from 201.3 million to 145 million years ago, the Jurassic was a time of global change in the continents, oceanographic patterns, and biological systems. On land, dinosaurs and flying pterosaurs dominated, and birds made their first appearance.Late Palaeozoic to early Mesozoic eras Triassic. During the Triassic Period, a hot and dry environment led to the deposition of sandstones, salts and mudstones in deserts, rivers and shallow lakes. Reptiles were common and the first dinosaurs evolved. Permian. During the Permian Period, Britain lay on the supercontinent of Pangaea and experienced hot, dry …

Living gymnosperms are distributed worldwide, excepting polar regions, the highest mountains, the driest deserts, and a few oceanic islands. The cycads are primarily tropical and subtropical, with greatest diversity in Central America, Africa and Australia. Ginkgo is confined to a very small native range in China.Many plants and animals disappear abruptly from the fossil record as one moves from layers of rock documenting the end of the Cretaceous up into rocks representing the beginning of the Cenozoic (the era after the Mesozoic). Between the last layer of Cretaceous rock and the first layer of Cenozoic rock, there is often a thin layer of clay.Following the Mesozoic era was the Cenozoic, which began about 66 million years ago. This period is also known as the "Age of Mammals," as large mammals, following the extinction of the dinosaurs, became the dominant creatures on the planet. In the process, mammals diversified into the many species still present on the Earth today.
The Mesozoic was a time of significant tectonic, climatic, and evolutionary activity. The era witnessed the gradual rifting of the supercontinent Pangaea into separate landmasses that would move into their current positions during the next era. The climate of the Mesozoic was varied, alternating between warming and cooling periods.Where Dinosaurs Lived. Dinosaurs lived over 180 million-year span that ranged from the Triassic Period when all continents were joined as a single landmass known as Pangea beginning 250 million years ago through the Cretaceous Period ending 66 million years ago. The Earth looked a lot different during the Mesozoic Era, from 250 million to 65 ...Quaternary to Mesozoic. Figure D.13-1 shows the geologic time scale indicating the breakdown of geo-logic time units and corresponding ages. The proposed route in Arizona generally traverse alluvial plains, alluvial fans and pediments, and sev-eral mountain ranges. The California segments of the route generally cross alluvial plains and valleys,The Mesozoic Era is known as the “Age of Reptiles.” Today's reptiles represent only a fraction of the reptile groups and species that have lived. Reptile - Evolution, Paleontology, Adaptation: The first land vertebrates, the Tetrapoda, appeared near the middle of the Devonian Period. The earliest known reptiles, Hylonomus and Paleothyris, date from the …Of the many species on earth today that can trace their ancestry back to prehistoric times, evolution has touched crocodiles perhaps least. Along with pterosaurs and dinosaurs, crocodiles were an offshoot of the archosaurs, the "ruling lizards" of the early-to-middle Triassic period of the Mesozoic Era. This epoch in history began about 251 ...

The biggest prehistoric snake that ever lived, Titanoboa measured 50 feet from head to tail and weighed in the neighborhood of 2,000 pounds. The only reason it didn't prey on dinosaurs is because it lived a few million years after the dinosaurs had gone extinct! See 10 Facts About Titanoboa. 12.The Paleozoic is bracketed by two of the most important events in the history of animal life. At its beginning, multicelled animals underwent a dramatic "explosion" in diversity, and almost all living animal phyla appeared within a few millions of years. At the other end of the Paleozoic, the largest mass extinction in history wiped out approximately 90% of all …
