But they evolved from a flying ancestor, were actual giants for millions of years, and some of them were even dressed a little more casually. Thank you to these paleoartists for allowing us to use their wonderful penguin illustrations: Ceri Thomas: http://alphynix.tumblr.com/ Stanton Fink: https://www.deviantart.com/avancna Nobu Tamura: https://spinops.blogspot.com/ Julio Lacerda (cretaceous predator illustrations!): https://252mya.com/gallery/julio-lacerda Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios Super special thanks to the following Patreon patrons for helping make Eons possible: Anthony Callaghan, Anton Bryl, Jeff Graham, shelley floryd, Laura Sanborn, Henrik Peteri, Zachary Spencer, Chandler Bass, Richard Ohnemus, Joao Ascensao, Andrey, Ben Thorson, Marcus Lejon, Ilya Murashov, Nathan Paskett, Jerrit Erickson, Merri Snaidman, David Sewall, Gabriel Cortez, Jack Arbuckle, Kevin Griffin, Robert Noah, Philip Slingerland, Todd Dittman, James Bording, Eric Vonk, Robert Arévalo, Esmeralda Rupp-Spangle, Jon Monteiro, Missy Elliott Smith, Jonathan Wright, Gregory Donovan, Miles Chaston, Michael McClellan, PS, Maria Humphrey, Larry Wilson, Hubert Rady, John Vanek, Tsee Lee, Daisuke Goto, Gregory Kintz, Matt Parker, Tyson Cleary, Case Hill, Stefan Weber, Betsy Radley If you d like to support the channel, head over to http://patreon.com/eons and pledge for some cool rewards!
