Wikipedia article of the day for January 21, 2020
The Wikipedia article of the day for January 21, 2020 is Onychopterella.
Onychopterella was a predatory aquatic arthropod of the order of eurypterids, often called sea scorpions. Fossils of the species O. kokomoensis (pictured) and O. pumilus have been found in the United States, and fossils of O. augusti in South Africa. Onychopterella (from Greek for 'claw wing') lived from the Late Ordovician to the Late Silurian, from 444 to 422 million years ago. The head was almost rectangular, with bean-shaped compound eyes. The limbs were generally long and narrow with a spine on the tip, and the body was ornamented with small, pointed scales. Lengths ranged from 16 cm (6.3 in) for O. kokomoensis to 4 cm (1.6 in) for O. pumilus. Onychopterella was able to swim, and probably able to walk on the seabed with its spines and dig with its head. The best-preserved specimens of O. augusti show similarities to modern scorpions in their alimentary canal, limb musculature and respiratory system.

Wikipedia article of the day for January 20, 2020
The Wikipedia article of the day for January 20, 2020 is Buzz Aldrin.
Buzz Aldrin (born January 20, 1930) is an American former astronaut and fighter pilot. As lunar module pilot on the Apollo 11 mission, he and Neil Armstrong were the first humans to land on the Moon. A graduate of West Point and MIT, where he earned a doctorate in astronautics, Aldrin served as an Air Force fighter pilot during the Korean War, flying 66 combat missions and shooting down two MiGs. He was selected as an astronaut with NASA's third group in 1963. His first spaceflight was in 1966 on Gemini 12, during which he spent over five hours outside the spacecraft. He set foot on the Moon on July 21, 1969 (UTC), nine minutes after Armstrong. He left NASA in 1971 and became commandant of the U.S. Air Force Test Pilot School. His autobiographies Return to Earth and Magnificent Desolation recount his struggles with depression and alcoholism. He developed the Aldrin cycler, a Mars spacecraft trajectory, and continues to advocate for space exploration, particularly a human mission to Mars.
