What phylum does Elrathia belong to?

What phylum does Elrathia belong to?


Elrathia Temporal range: Middle Cambrian,
Kingdom: Animalia
Phylum: Arthropoda
Class: †Trilobita
Order: †Ptychopariida

What era is Elrathia Kingi?

Cambrian period
These are specimens of Elrathia kingii, a Cambrian period trilobite from the Wheeler Shale in Utah, some 515 Million years old.

Is Elrathia extinct?

Elrathia is an extinct genus of ptychopariid trilobites that lived in the Middle Cambrian, in Utah and possibly, British Columbia. It is one of the most common trilobites in USA. 1950 specimens of Elrathia are known from the Greater Phyllopod Bed, where they comprise 3.7% of the community.

What environment did Elrathia live in?

Elrathia trilobites could survive in low oxygen environments, lower than what most living things could survive. Fun Fact 2: Living in low oxygen areas allowed these trilobites to easily fossilize. This makes them the most common trilobite fossil in North America.

What is a Cambrian sponge?

Sponges (phylum Porifera) are commonly represented in Cambrian faunas. Archaeocyathan sponges, characterized by cup-shaped skeletons with double calcareous walls and numerous pores, are abundant and diverse in some early Cambrian deposits.

What is the scientific name for the phylum that represents the most abundant fossil animals and the top predators during the Cambrian period?


Trilobite Temporal range: Early Cambrian – Late Permian,
Kingdom: Animalia
Phylum: Arthropoda
(unranked): †Artiopoda
Subphylum: †Trilobitomorpha

When did Trilobites go extinct?

252 million years ago
These ancient arthropods filled the world’s oceans from the earliest stages of the Cambrian Period, 521 million years ago, until their eventual demise at the end of the Permian, 252 million years ago, a time when nearly 90 percent of life on earth was rather suddenly eradicated.

How common are trilobite fossils?

Best estimates put this number to over 20,000 species. Trilobites are one of the most successful animals to live on Earth. They were already here before the Cambrian explosion, survived numerous mass extinctions and lived until the end Permian extinction event, the end of the Paleozoic age.

What is the most common trilobite?

Elrathia kingii, the world’s most common trilobite, is one of the species found in this order. Over 50,000 Elrthia specimens have been found, many in the Wheeler Shale of Utah .

How big can a trilobite get?

Many trilobites were 3–6 cm long, but some such as Paradoxides were giants, up to 60 cm or more, while others like the tiny, blind agnostid trilobites were no more than a few millimetres long.

Where can I hunt trilobites in Utah?

In Utah, trilobites can be found at several localities. The Wheeler Amphitheater in the House Range, Millard County is one of the more well-known collecting areas. Most of the trilobites in this area come form the Middle Cambrian formation called the Wheeler Shale.

Is Flint Fossilised sponge?

Among the most commonly found flint fossils include sponges, echinoids, shells and of course trace fossils i.e. burrows.

Who was the first animal?

The First Animals Sponges were among the earliest animals. While chemical compounds from sponges are preserved in rocks as old as 700 million years, molecular evidence points to sponges developing even earlier.

What phyla UM are typical and/or most important in the marine Cambrian fauna select all that apply?

Cambrian faunas, like those of the present day, are commonly dominated in numbers and kind by members of the phylum Arthropoda.

What organisms disappeared during the Cambrian Period?

The end of the Cambrian saw a series of mass extinctions during which many shell-dwelling brachiopods and other animals went extinct. The trilobites also suffered heavy losses.

Could trilobites still exist?

Probably not. Trilobites have been extinct since before the age of Dinosaurs (about 251 million years ago), but some living creatures bear such close superficial resemblance to trilobites that they cause great excitement when encountered.

Is a horseshoe crab a trilobite?

Horseshoe crabs are often cited as the closest living relatives of trilobites, but they are no more closely related than any other creature in the Chelicerata phylum. Horseshoe crabs are members of the Limulidae family. Although they have the name “crab,” they aren’t closely related to them at all!

What is the genus of a trilobite?

Phillipsia, genus of trilobites (an extinct group of aquatic arthropods) uncommonly found as fossils in Carboniferous and Permian rocks (about 251 million to 359 million years old) in Europe, North America, and the Far East.

Do trilobites bite?

They had a variety of different feeding methods and no jaws but they still had their own unique ways to “bite”. But don’t worry your toes are safe; trilobites died off 252 million years ago.

What’s the biggest trilobite?

Isotelus rex
Isotelus rex: The “king”… this 28 inch specimen from Churchill, Manitoba holds the current record for trilobite size. Isotelus latus: Another large Canadian asaphid, this Ordovician species routinely reached lengths of 10 inches.

Where can I get a free trilobite in Utah?

Where can I dig for trilobites?

Another prime spot for trilobites, U-dig Fossils in Utah has a 40-acre quarry with loads of gems to find. They claim that the average visitor can find ten to twenty trilobites in a four-hour period, along with brachiopods, sponges, worm tracks, phyllocarids and other mid-Cambrian fossils.
