How might scientists reconstruct modern animals years into the future? This is a breakdown of “All Todays” — a thought experiment from the “All Tomorrows” author C. M. Kosemen, with John Conway and Darren Naish. Imagine what would happen if, millions of years into the future, scientists — perhaps from other planets — tried to create depictions of the long extinct organisms they found in Earth’s fossil record. This concept is part of a thought experiment, “All Todays,” written in part by the astonishing author C. M. Koseman — whose work you might have seen from his other most famous book “All Tomorrows.” “All Todays” is a section in the larger 2012 art book “All Yesterdays,” dreamed up by not just C. M. Kosemen, but Darren Naish — a renowned zoologist, paleontologist and author, and John Conway: an immensely talented paleo-artist.
