Dinosaurs

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.

The Paleogene Period followed the Cretaceous.

Yes, but they choose not to.

Archaeologists concern themselves with human and societal development (like anthropologists) and as such they deal with remains that are too young to have fossilized. If an archaeologist wanted to, they certainly could apply their skills to paleontology, but they leave that to the paleontologists just like the paleontologists leave anthropology to archaeologists and anthropologists.

Remember that dinosaurs were the precursors of birds and they were also reptiles. Birds and amphibians, male and female, have a sexual organ called a cloaca which they would press together to exchange sperm. However, reptiles do have an internal penis, that only appears externally during sex, which would be used with the female's cloaca.

No, although modern reptiles and dinosaurs do share common ancestors that lived in the distant past (likely the Carboniferous epoch). Birds, however, evolved from dinosaurs in the Jurassic epoch.

It depends on the size of it. It can really be any amount. We have a couple that are about the size of an apple (but flatter), and those were about 10 bucks probably. But they can probably get really expensive too!

The root word "saur" means lizard or reptile. It is commonly found in the names of dinosaurs, such as Tyrannosaurus, meaning "tyrant lizard," indicating their reptilian nature.

No one knows if any dinosaurs have a frill, but you are probably thinking of Dilophosaurus.

No dinosaurs lived in the sea. There were other reptiles that adopted a marine life, but those weren't dinosaurs.

Dinosaurs are more closely related to reptiles than to amphibians.

In fact, dinosaurs are classified as reptiles.

Amphibians are lower on the evolutionary tree than reptiles. Reptiles developed from amphibians. Amphibians developed from fish.

There were a number of long-necked dinosaurs. One was the brontosaurus.

Protoceratops belongs to the Ceratopsidae family, which is further divided into subfamilies such as Protoceratopsinae and Ceratopsinae. These subgroups are based on differences in skull anatomy, size, and other characteristics among different species of Protoceratops and related dinosaurs.

Dinosaurs belong to the taxonomic group of reptiles known as Dinosauria. They are further categorized into various families, such as Tyrannosauridae, Stegosauridae, and Hadrosauridae, based on their specific characteristics and evolutionary relationships.

The two major groups of dinosaurs are the saurischians and ornithischians. Saurischian dinosaurs include theropods like T. rex and sauropods like Brachiosaurus, characterized by their hip structure. Ornithischian dinosaurs include species like Triceratops and Stegosaurus, known for their distinctive beaks and herbivorous diets.

Hadrosaurids or duck-billed dinosaurs are members of the family Hadrosauridae, and include ornithopods such as Edmontosaurus and Parasaurolophus.

Saber-toothed cats belong to the Felidae family, which includes all living and extinct cats. They are a subfamily within Felidae called Machairodontinae, known for their elongated canines and adaptations for hunting large prey.

It's a question of chronology, time.

Dinosaurs appeared long before humans. Then, due to a meteor strike the climate on earth changed and the dinosaurs died out. Long after that, humans appeared.

If the meteor hadn't struck, dinosaurs would probably have lived on.

Or maybe they'd still been beaten by the mammals, only slower.

And maybe humans had never appeared. O maybe we had. No one can tell.

During the time of dinosaurs, early mammals, birds, and various reptiles lived alongside them. The majority of dinosaurs roamed the Earth during the Mesozoic Era, particularly during the Triassic, Jurassic, and Cretaceous periods. These creatures inhabited different regions around the globe, from forests and swamps to deserts and plains.

No. Dinosaurs and cavemen are separated by about 65 million years of earth history.

This is a pretty touchy issue for most old school catholics. This is because there is very little/no mention of dinosaurs in the bible (Although check out Job, it mentions a scaled land beast with legs like trees, and a massive water beast that belches flames and scare angels and no weapon can break it's hide). They also believe that Adam and Eve were the first people and after them came Cain and Abel and then eventually Noah, Abraham and so on; so it's hard for them to believe in cave men too.

Luckily some more liberal open Catholics can believe in the bible AND not ignore scientific evidence.

The first key hominid trait to appear in the fossil record is bipedalism, which refers to the ability to walk upright on two feet. This adaptation is characteristic of early hominids and distinguishes them from their primate ancestors.

The first hominids, known as Australopithecus, appeared during the Pliocene epoch, around 4 to 5 million years ago in Africa. These early hominids walked upright and had a mixture of ape-like and human-like features.

There was no such thing as a tyranasourous-rex There was a Tyrannosaurus Rex which was around in prehistoric times though.

Dinosaurs first appeared around 230 million years ago and are popularly said to have gone extinct 65.5 million years ago. However, in a sense dinosaurs are still alive since most paleontologists now classify birds as dinosaurs.

Dinosaurs were on earth a long time before neanderthal.

Dinosaurs lived on earth from about 230 to 65 million years ago.

Neanderthal features started to evolve around 650,000 years ago (over 64 million years after the extinction of the dinosaurs) and the 1st true neanderthals appeared about 130,000 years ago.
