Question: Where is the Burgess Shale located and why is it important?

The Burgess Shale is a fossil-bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. It is famous for the exceptional preservation of the soft parts of its fossils. At 508 million years old (middle Cambrian), it is one of the earliest fossil beds containing soft-part imprints.The Burgess Shale is a fossil-bearing deposit exposed in the Canadian Rockies of British Columbia, Canada.

Why is Burgess Shale so important?

The Burgess Shale has contributed significantly to the fossil record because of the large number of well preserved fossils found within its layers. These fossils exemplify a unique method of preservation. In the Burgess Shale however, organisms lived in underwater mud banks known as phyllopod beds.

Where is the Burgess Shale located?

British Columbia Burgess Shale/Province

What is the significance of the Burgess Shale quizlet?

What is importance of the Burgess shale fauna? It contains Cambrian fossils (over 100,000 fossils) of more than 130 animal species. It was very complex community of animal species. There was a huge variety of body forms.

What caused the Burgess Shale?

The Burgess Shale fossils are preserved in a type of sedimentary rock known as shale. The compressed seafloor muds of the Burgess Shale were transformed into shale when they encountered increased temperature and pressure during their geological history.

What age is the Burgess Shale?

More than half a billion years old, the fossils of the Burgess Shale preserve an intriguing glimpse of early life on Earth. They were first discovered in 1909 by Charles D. Walcott, then Secretary of the Smithsonian Institution.

What was the largest predator of the Cambrian?

Titanokorys Titanokorys was one of the biggest ocean predators of the Cambrian period (543 million to 490 million years ago) and is the largest-known Cambrian seafloor predator, according to a new study.

What was found in the Middle Cambrian Burgess Shale?

Most importantly, the Burgess Shale tells of the Cambrian explosion, a huge radiation of marine animal life that included sponges, soft bodied arthropods and those with hard exoskeletons, the first chordates, worms, and trilobites, as well as the strange spiked creatures such as Wiwaxia, and the large predator ...

What is unusual about the fossils in the Burgess Shale answers?

Fossils of chordates, the phylum to which humans belong, are very rare in Cambrian sediments. Conway Morris classified the Burgess Shale fossil Pikaia as a chordate because it had a rudimentary notochord, the rod of cartilage that evolved into the backbone of vertebrates.

What is the Burgess Shale quizlet?

The Burgess Shale Formation is a fossiliferous deposit exposed in the Canadian Rockies of British Columbia, Canada. [2] It is famous for the exceptional preservation of the soft parts of its fossils. At 508 million years (Middle Cambrian) old,[3] it is one of the earliest fossil beds containing soft-part imprints.

How did the Burgess Shale fossil bed form?

Sediment flowing into the sea buried both dead and living animals. As more and more sediment accumulated, the organisms were compressed and fossilized. As this process repeated, the layers of fossils now found in the Burgess Shale were created.

What was before the Cambrian explosion?

Before the Cambrian period, there lived a smattering of weird creatures referred to as the Ediacarian biota. Oldest among these bizarre organisms was a floppy 1.5-meter-long bathmat of a creature known as Dickinsonia.

Who found the Burgess Shale?

Charles D. Walcott More than half a billion years old, the fossils of the Burgess Shale preserve an intriguing glimpse of early life on Earth. They were first discovered in 1909 by Charles D. Walcott, then Secretary of the Smithsonian Institution.

What is the biggest animal in the world that is still alive?

blue whale The largest living animal in the world is the blue whale (Balaenoptera musculus), a beast measuring upwards of 100 feet (30 meters) long. But enough about the whale.

What fossils were found in the Cambrian period?

CMN 344 Cambrian/Fossils

What components of the Burgess Shale are the rarest?

GEO ExPro - Rarest of All - The Burgess Shale Fossils.

What type of rock is found in the Burgess Shale?

sedimentary rock The Burgess Shale fossils are preserved in a type of sedimentary rock known as shale. Shale is a variety of mudstone (originally formed from deposits of fine mud) that can be easily split apart.

What did the Burgess Shale eat?

Sidneyia was a large 13 centimetres (5.1 in) long predator of the Burgess Shale, and ate trilobites, ostracods, and hyolithids. It was named after Walcotts second son, Sidney.

What did life look like before the Cambrian Explosion?

Before the Cambrian explosion, most organisms were relatively simple, composed of individual cells, or small multicellular organisms, occasionally organized into colonies. As the rate of diversification subsequently accelerated, the variety of life became much more complex, and began to resemble that of today.

What animals existed before Cambrian Explosion?

Before the Cambrian period, there lived a smattering of weird creatures referred to as the Ediacarian biota. Oldest among these bizarre organisms was a floppy 1.5-meter-long bathmat of a creature known as Dickinsonia.
