One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized.

Demon Attack (atarionline.org) Demon Attack is a game for the Atari 2600 developed by Imagic in 1982. Although it is said to be inspired by the 1979 arcade game Galaxian, its gameplay and visuals are more closely related to some waves from the 1980 arcade game Phoenix. This similarity led to a lawsuit from Atari, Inc., who had acquired the home video game rights to Phoenix. The dispute was eventually settled out of court, and despite the legal challenge, Demon Attack went on to become Imagic’s best-selling game as of 1983.

Silurian (Wikipedia) The Silurian (/sɪˈljʊəriːən, saɪ-/ sih-LURE-ee-ən, sy-) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at 443.8 million years ago (Mya), to the beginning of the Devonian Period, 419.2 Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period’s start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out.
