Most of what scientific know about extinct species is based on?
Most of what scientists know about extinct species is based on the study of bones and fossils. Scientists have studied many dinosaur bones to determine what they ate and how they lived. Fossils tell what the land was like at a given time in history.
Do beetles make their own light?
Most beetles do not produce light, but a few species do. Most notable are fireflies.
How many bones does a reptile have?
The number of bones depends on the species.
How heavy are bird bones?

Why are bones are so light?
Bones are light because they are hollow in the middle.
What percentage of animals on earth don't have back bones?
These numbers are not accurate, as accurate number of animal species on earth has yet to be discovered. Currently it looks like less than 3% of the known species of animals on earth are vertebrates (have back bones). There are around 50 000 species of vertebrates, most of which are fish. Most animals are invertebrates, and most of those are insects.Read more:What_percent_of_animals_on_earth_have_a_backbone

How many bones dinosaurs have?
We haven't found enough bones yet, except for one species: tyrannosaurus rex. It's all thanks to Sue: the biggest and most complete T-rex. T-rex had about 200 bones in its body: roughly around how many bones we have.
Do 95 percent of known species have bones?
No. Many animal species have an exoskeleton or no skeleton at all. The huge amount of animals that fall into these two categories makes it impossible for 95% of known species to have bones. Insects make up over half of the known species. Insects have an exoskeleton and do not have bones like humans and other vertebrates do. Since more than 50% of species are insects and therefore have an exoskeleton, it is impossible for more than 50% of species to have bones.
What species has 206 bones?
Homo sapiens, modern man, has 206 bones in the adult skeleton.
What bones do humans most frequently?
The most commonly broken bones in humans are the wrist bones, in particular the radius and ulna. This often occurs due to falls or accidents where people instinctively try to break their fall with their outstretched hands. Additionally, fractures in the ankle and collarbone are also quite common.
