Dinosaurs, Birds, and Change The Triassic Period – roughly 251 to 199 million years ago. Around 245 million years ago the first dinosaurs appeared. This was during what geologists call the Triassic Period – the first period of the Mesozoic Era. Dinosaurs were reptiles and they had been preceded for millions of years by other reptiles on land. Conditions had allowed the survival of the larger reptiles, whose size helped them survive.

- Dinosaurs walked the Earth for an incredible 165 million years. They first appeared in the late Triassic Period, before diversifying to dominate the planet, and become the largest land animals to have ever lived. However, 65 million years ago, the reign of the dinosaurs was to come to an abrupt end. An event so monumental occurred that it changed the shape of our planet forever. Evidence points to a giant asteroid which smashed into the Earth, leaving a crater nearly 200km wide.

Dinosaurs and the Bible When Did Dinosaurs Live? The story we have all heard from movies, television, newspapers, and most magazines and textbooks is that dinosaurs lived millions of years ago. According to evolutionists, the dinosaurs “ruled the Earth” for 140 million years, dying out about 65 million years ago. However, scientists do not dig up anything labeled with those ages. They only uncover dead dinosaurs (i.e., their bones), and their bones do not have labels attached telling how old they are.

Great White Shark THE DEVONIAN PERIOD (about 410 to 360 million years ago) THE FIRST LAND ANIMALS EVOLVE.

Slugs in home gardens Slugs in home gardens. Slugs can be very damaging pests in moist, shady gardens. They feed on the leaves of many plants, especially seedlings. Later in the season they can feed on ripening fruits and vegetables. Slugs are especially numerous during rainy seasons and in well-irrigated gardens. If slugs are abundant one year, it does not mean they will be as common the following season; the relative number of slugs in a given season depends on how moist the growing conditions are.
