Africa's fossil beds anchor this Paleoworld episode, the second half of a two-part look at the continent's dinosaur discoveries. The series follows paleontologists across Niger's deserts and Tanzania's plains, tracing finds that reshaped ideas about African prehistory. A field researcher walking back to camp turns up the remains of Deltadromeus, and a later climb up a cliff face uncovers the skull of Carcharodontosaurus, though the show never names either fossil on screen. Spinosaurus gets the most attention: first described from Egyptian remains in the early twentieth century, it's rebuilt here through expert interviews and period-appropriate CGI that gives a sense of its size and hunting style. The episode also credits the people behind the science, from Mary Leakey's early work to Paul Sereno's expeditions, framing African paleontology as a continuing excavation rather than a finished catalog. Interviews with working paleontologists explain how partial skeletons and scattered bone beds get pieced into full animals, and how much of the continent's fossil record is still being read for the first time.
