What types of organisms were dominant after the Devonian mass extinction?

The Devonian extinction ushered in not only the land-bound tetrapods, but also the animals that command the marine vertebrate world to this day: ray-finned (or bony) fish, and cartilaginous fish, like sharks, rays and chimeras.

What types of plants lived during the Silurian period?

Bryophytes such moss, hornworts and liverworts first appeared in the late Ordovician. The first known plant to have an upright stalk, and vascular tissue for water transport, was the Cooksonia of the mid-Silurian deltas.

What animals dominated during the Cenozoic Era?

Bovids, including cattle, sheep, goats, antelope and gazelle, flourish during this period. Cave lions, sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary period.

What organisms dominated the Mesozoic?

The dominant land animals were reptiles. The first dinosaurs, marine reptiles, lizards, and tortoises appeared. Mammals appeared during the Triassic, but they remained insignificant until their competitors, the dinosaurs, became extinct at the end of the Cretaceous.

What organisms survived the Late Devonian mass extinction?

Although freshwater fish were barely affected, marine animals were much more so. Placoderms, for example, did not survive, acanthodians were decimated, and almost all agnathans vanished. Numerous brachiopods became extinct, conodonts all but disappeared, and only one family of trilobites survived.

What group of organisms developed rapidly in the Silurian period?

The other main important group to develop rapidly in the Silurian were fish. Fish were colonizing freshwater rivers and lakes from the sea, ready for the eventual evolution to land based organisms. Fungi are believed to have diversified during the Silurian but these organisms rarely fossilize at all.

What are some Silurian animals?

Millipedes are some of the oldest terrestrial animals on Earth. Silurian organisms lived during the Silurian period, which lasted between 443.7 and 416 million years ago. The Silurian is the shortest geologic period aside from the Neogene, with a total length of just 27.7 million years.

What was new life like in the Silurian period?

The new life in the Silurian Period was the coral reef. Tabulate corals and rugose corals formed these reefs in the Silurian rocks. Tabulate corals lived in colonies that formed chains. The chains sometimes looked like clumps of organ pipes.

Did starfish exist during the Silurian period?

The beginning of the Silurian is defined by a series of extinction events, so severe that they wiped out 60% of all animals, the second largest mass extinction in history. Starfish existed during the Silurian period.
