October 4, 2025 - Age of Dinosaurs is a 2013 American science fiction action film directed by Joseph J. Lawson and starring Ronny Cox and Treat Williams. Using flesh-regeneration machines, Genetisharp (a biotech company) creates a set of living dinosaurs and pterosaurs from a strand of DNA.

1 week ago - Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is a subject of active research.

2 weeks ago - Overall, however, the Earth was hotter than it is today. Dinosaurs first appeared in the Mid-Triassic, and became the dominant terrestrial vertebrates in the Late Triassic or Early Jurassic, occupying this position for about 150 or 135 million years until their demise at the end of the Cretaceous.

October 5, 2025 - As dinosaur fossils are usually preserved in solid-rock boulders or covered in thick bands of ironstone matrix, it is often a long and time-consuming task to chisel the rock away. Work undertaken at the Australian Age of Dinosaurs Laboratory includes mechanical preparation of the bones with pneumatic scribes, which remove rock from the bones.

1 month ago - Age determination in dinosaurs is mainly used to determine the approximate ontogenetic age of a dinosaur when the animal died. Early attempts to estimate the longevity of dinosaurs used allometric scaling principles. Ages were determined by dividing individual mass estimates by rates of growth ...

March 21, 2025 - Evolution also brought us dinosaurs, notes this paleontologist at the University of Scotland in Edinburgh. And, he adds, they “thrived for over 150 million years.” But to do so, they had to adapt to many different types of climate and ...

Dinosaurs first appeared in the Triassic Period, around 245 million years ago ... Explore the age of the dinosaurs.

March 6, 2021 - The Mesozoic Era is literally the era of “middle life.” It is also known as the age of dinosaurs. It lasted from 245 to 65 million years ago and is divided into the three periods described inFigure below.

October 22, 2025 - The following outline is provided as an overview of and topical guide to dinosaurs: Dinosaurs – diverse group of animals of the clade and superorder Dinosauria.

January 30, 2023 - Dinosaurs lived during the Mesozoic Era (252 to 66 million years ago), often called the “Age of Dinosaurs.” The Mesozoic Era is divided into three time periods, the Triassic, Jurassic, and Cretaceous.

July 21, 2024 - In brief, this incredibly long period of time, which the dinosaur periods span, measured in "mya" or "millions of years ago," saw the development of dinosaurs, marine reptiles, fish, mammals, flying animals including pterosaurs and birds, and a huge range of plant life. The largest dinosaurs did not emerge until the Cretaceous period, which started over 100 million years after the start of the "age of dinosaurs."

They were the dominant vertebrate animals of terrestrial ecosystems for about 170 million years, from the late Triassic Period (about 243-233 million years ago) until the end of the Cretaceous period (66 million years ago), when most of them ...

Most of the major groups of dinosaurs evolved during the Jurassic Period (approximately 201 million to 145 million years ago). Together the Triassic, Jurassic, and Cretaceous periods make up the Mesozoic Era, also called the Age of Dinosaurs ...

All dinosaurs (aside from birds) lived and died in the Mesozoic Era. The Mesozoic (252 to 66 million years ago) was the "Age of Reptiles." Dinosaurs, crocodiles, and pterosaurs ruled the land and air.

July 6, 2021 - Dinosaurs ruled the Earth for 135 million years. There were many types of dinosaurs, in all shapes and sizes.

The 'Age of Dinosaurs' (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods.
