 For example, artists that pioneered anatomically rigorous reconstructions of fossil hominids, like Jay Matternes and Alfons and Adrie Kennis, as well fossil mammal paleoartist Mauricio Antón, were lauded by Conway and colleagues as seminal influences in the new culture of paleoart.Other modern paleoartists of the "anatomically rigorous" and "All Yesterdays" movement include Jason Brougham, Mark Hallett, Scott Hartman, Bob Nicholls, Emily Willoughby and Mark P. Witton.Other authors write in agreement that the modern paleoart movement incorporates an element of "challenging tropes and the status quo" and that paleoart has "entered its experimental phase" as of the dawn of the 21st century.
