Many animals that evolved during the Cambrian period, 541 million to 485 million years ago, seem bizarre compared with modern life-forms. Even paleontologists sometimes wonder: Why do Cambrian creatures look so strange? He concluded that the animal probably used its awkward facial appendage to dig for food.

What animals came out of the Cambrian explosion?

More than 20,000 fossil specimens were collected, including many soft bodied animals such as jellyfish, sea anemones and worms, as well as sponges, arthropods and algae.

What is the most famous fossil from the Cambrian?

Burgess Shale
This flourishing, called the Cambrian explosion, took place within about 25 million years. Fossils from the period have been preserved in rocks at more than 50 known sites worldwide, the most famous of which is Canada’s Burgess Shale, discovered in 1909.

What is Cambrian animal?

The Cambrian period, part of the Paleozoic era, produced the most intense burst of evolution ever known. The Cambrian Explosion saw an incredible diversity of life emerge, including many major animal groups alive today. Among them were the chordates, to which vertebrates (animals with backbones) such as humans belong.

• A receding of the Pre-Cambrian ice age – allowed for warmer more oxygenated seas.
• An increased capacity to foster life then arose.
• In this environment there was an unimaginable radiation of species.

What are some Cambrian organisms?

Here are some life forms that first appeared in the Cambrian period, with the oldest ones first: First Cnidaria, and probable annelids, about 580 million years ago, in the Ediacaran period. Small shelly fossils (SSF), including first molluscs and brachiopods, about 537 million years ago. First trilobites, about 526 million years ago. First echinoderms, about 522 million years ago. First crustaceans, about 510 million years ago.

What was life like in the Cambrian Period?

Trilobites were the dominant species during the Cambrian Period, 540 to 490 million years ago. The Cambrian Period is the first geological time period of the Paleozoic Era (the “time of ancient life”). This period lasted about 53 million years and marked a dramatic burst of evolutionary changes in life on Earth, known as the ” Cambrian Explosion .”.
