There is very little evidence for any plant life in the Precambrian Period. There is evidence in the form of stromatolites (found near Shark Bay in Australia) for bacteria. Some controversial fossils from the 1.25 billion year old Hatakai Shale from the Grand Canyon in the USA suggest that there was plant life in the Precambrian. Creationalist often use this as evidence that evolution is not true.
"Caveman" is not a very precise description for prehistoric humans since some people still live in caves. The animals that were contemporaries with prehistoric humans include most of those that are alive today and those that have gone extinct during the million or so years that humans can be identified from the fossil records. All modern birds and several extinct species such as the dodo and passenger pigeon would have coexisted with prehistoric humans. The wooly mamoth, saber-tooth tiger, and cave bear were depicted in cave drawings or were present in fossil records. It is probable that wolves were living with the early humans but were probably not yet domesticated as dogs. See the link for more detailed information on some of the animals that were contemporaries of North American humans from the last ice age.

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.
well I look to something and it said they are predators so.....

Over 250 million years ago.
