Hippos -- descendants from a small herd introduced by drug kingpin Pablo Escobar -- are seen in the wild in a lake near the Hacienda Napoles theme park, once the private zoo of Escobar, in Doradal, Antioquia Department, Colombia, on April 19, 2023. - Colombia is making progress on the transfer of 70 hippos to overseas sanctuaries in Mexico and India, but mitigating the havoc caused by this unusual legacy of deceased drug lord Pablo Escobar carries a hefty price tag: $3.5 million. The cocaine baron brought a small number of the African beasts to Colombia in the late 1980s, but after his death in 1993 the animals were left to roam freely in a hot, marshy area of Antioquia department, where environmental authorities have been helpless to curb their numbers which now stand at more than 150 animals.

In the aftermath of the Chicxulub impact weeks or months earlier, the last remaining non-avian dinosaurs struggle to eke out an existence. The heat from infalling debris initially led to a rise in temperature so great that many animals would have been killed within days. Weeks later, our planet's atmosphere is choked with soot, dust and other deposits, cutting off the Sun, and global temperatures have plummeted. Without the Sun for photosynthesis, plants die off worldwide, collapsing the food chain. Here, a lone, injured and half-starved Dakotaraptor surveys the remains of her territory in what will be known, 66 million years later, as Hell Creek.
