Is it true that most of the dinosaurs in the Cretaceous period where horned?
No.
What do most scientist think caused the mass extinction of dinosaurs and other organisms at the end of the Cretaceous Period?
A meteor hit the earth and caused severe condition that organisms could not survive.
What order do these go in tertiary Jurassic Quaternary Triassic cretaceous?
The correct order from oldest to youngest is Triassic, Jurassic, Cretaceous, and then Quaternary. The Triassic period is the earliest of the four, followed by the Jurassic, then the Cretaceous. The Quaternary period is the most recent.
How old r the Rocky Mountains?
Most likely during the Precambrian, Cretaceous PERIOD
During which period the dinosaurs disappeared on the Earth?
The Cretaceous / Tertiary boundary (KT) occurred 65 million years ago and extinctions of most dinosaurs was probably due to a meteorite impact in the Yucutan peninsular of Mexico known as the Chixulub crater.
What order (from oldest to most recent) are Jurassic cretaceous Permian Triassic and Cambrian?
The correct order from oldest to most recent is Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, and Cretaceous. The Cambrian period marks the beginning of the Paleozoic Era, while the Cretaceous period is the last of the Mesozoic Era. The Permian and Triassic periods follow the Paleozoic and precede the Mesozoic, with the Jurassic and Cretaceous periods occurring afterward.
What appeared near the beginning of the Cretaceous period?
The most notable group of organisms that evolved at the beginning of the Cretaceous are the flowering plants, or angiosperms. Today, these are the majority of plants on Earth. All fruit bearing plants and grasses are angiosperms. At the same time as these evolved, new insects evolved that pollinated the flowers. Additionally, birds evolved either during the late Jurassic or the early Cretaceous.

Most likely food and dinosaur repelant
Where do most of the organisms live in the rain forest?
Most organisms in the rainforest live in the trees.
What made the cretaceous period end?
The Cretaceous period ended as the result of a mass extinction event, probably resulting from an asteroid impact. This wiped out 65 percent of life on earth, including the ammonites, the plesiosaurs, the pterosaurs, and, most famously, the dinosaurs.
Most organisms on earth live in?
The air. Most organisms live in the air! others live in food and on your feet!!
