Were insects 100 million years ago as colorful as they are now?

Yes, 100 million-year-old insects are small but very "eye-catching", and they have some very rich colors, and most of the insect species show a strong metallic luster on the whole body or part of the body structure.

100 million years ago, many insects were as colorful as they are today. There are also a variety of them, and they are especially beautiful.

No, 100 million years ago, insects were mostly black and gray, and only a few were colorful.

Amber, as a work of art by nature, preserves the true appearance of many ancient creatures for us, so what is the obvious difference between the insects of 100 million years ago and the insects of today?

As the name suggests, the so-called worm amber is the amber that wraps the worm. In ancient times, insects and other creatures were wrapped in amber, and after a long time, they were discovered by humans now, but the flies in the worm were still very different from the flies of today.

100 million years ago, the fly in the worm was different from the current fly structure, the ancient fly head had an obvious protrusion, similar to an extra horn on the head, and above this horn, there are other sensory organs, because the position of the sensory organ on this horn is higher than the horizontal line of the fly, so it can better monitor the surrounding environment. And ancient flies, their antennae are also very peculiar in shape. Instead of having a linear antennae of the current fly, it has several branches, like the tentacles of an octopus in the sea, and the jaws of ancient flies are more delicately shaped, allowing for better ingestion of food.

According to the speculation of root calendarists, another obvious difference between insects from 100 million years ago and today's insects is that the insects of 100 million years ago were even larger because of the higher oxygen content in the earth in ancient times. One of the most critical limiting factors is the amount of oxygen in the air, and in ancient times, the oxygen content was much higher than it is now, and the harsh natural environment gave rise to larger insects. As for why these insects have not been preserved, it may be that the size is too large for amber to wrap, or it may be that those insects do not have hard bones, and their flesh and blood have been slowly worn away over time, and there is no way to preserve them.

So after talking about the obvious difference between insects 100 million years ago and now, let's take a look at the species that did not change between 100 million years ago and now, that is, sea turtles. Foreign biological researchers have found that the ancient turtle structure of 100 million-year-old sea turtle fossils, or sea turtle amber, is not much different from that of modern sea turtles, which may indicate that the marine environment has not changed much, so that the species has little chance to evolve.

There has been a noticeable evolution, and it looks very similar, and there has been a reduction in size, and there have been changes in color.

Their habits and ways of capturing will be different, and they have changed a lot, and their body size is relatively large.

The two are very similar in appearance, but they are not identical. Biological evolution is a process that is more adapted to the environment, and there are definitely local changes.

500 million years ago there were trilobites, seaweed, worms,

440 million years ago there were hornstones, 400 million years ago there were turtles, sea scorpions,

350 million years ago there were horned stone newts and total finned fish, 270 million years ago there were seal trees and finned lizards, and 225 million years ago there were kirosaurs.

180 million years ago there were Metasequoia and Lufeng Dragons, 135 million years ago there were Archaeopteryx, cycads and Mamenxi dragons, 70 million years ago there were pterosaurs and Tyrannosaurus rex, 3 million years ago there were thunderbeasts, horses, and so on.

Next up is the willow. and ape-man.

to the human race today.

The Cambrian period was the beginning of the Phanerozoic, about 542 million years ago - 488 million years ago. During this period, animals with hard shells appeared on Earth for the first time. Although the animals of the Cambrian period were marine animals, they rarely roamed the sea, but lived close to the bottom of the sea.

Many known Cambrian animals can be found in the Burgess Shale.

The biota is dominated by marine invertebrates, especially trilobites, lower brachiopods and paleocytes. Red algae, green algae, etc. began to flourish.
