In fossil form?
If so, in a range of fossil sediments! They are some of the most common fossils (In Paleozoic deposits anyway)
Animals common to the Bathyal zone include octopi, whales, squid, and sea stars. The climate is not friendly toward fish species, but sponges and brachiopods love it there.
well I look to something and it said they are predators so.....
The best type of rock to find fossils in is sedimentary rock this is laid down over time and will contain dead animal's, fish and crustaceans. Specific types are trilobites and brachiopods. Fossils can often be found in coal.
Brachiopod's have hard shells on the upper and lower surfaces, Their shell is hinged at the rear end, while the front can be opened for feeding or closed for protection.
Short spans of geologic time
brachiopods are formed from older brachiopods mating
Brachiopods are related to Brachiopods, they exist in the modern day just not as abundantly as in the past.
Brachiopods are also known as lamp shells. They are marine animals that have a lifespan that ranges from 3 to 30+ years.
Paleozoic
Most brachiopods became extinct about 250 million years ago during the P-T Extinction period. Modern day brachiopods do still exist in the form of lingula.
brachiopods
Trilobites first appeared in the fossil record in the Atdabanian stage of the Early Cambrian period. The fist brachiopods likewise first appeared in the Early Cambrian era.
Yes. Brachiopods were abundant in the Permian.
