It was found in the the Ocucaje desert, 217 miles south of Lima. It came from the Pisco geological formation – which contains a lot of well preserved marine fossils. These include the skeletons of four legged dwarf whales, dolphins, sharks. and so on. It dates to the Miocene era, 23 to 5 million years on the geological column. At https://en.wikipedia.org/wiki/Ocucaje_desert … we know that a lot of marine fossils have been extracted from the region, some of them going back 40 million years ago. The Canyon of the Lost is an interesting feature of the desert. It is an array of rock formations, steep sided cliffs, and winding paths carved over geological time by internal forces. This is standard uniformitarian interpretation and presumably they are referring to the slow process of water erosion. However, it could equally have formed, on several occasions, as a result of high velocity water. Whatever, the walls of the canyon are composed of sedimentary rock strata, representing layers of earth history. They contain fossils going back millions of years.
At https://phys.org/news/2025-10-early-humans-dined-giant-sloths.html … here we are told that early humans dined on giant sloths. This is according archaeologists in Argentina – and presumably paleontologists, too. What is the evidence? It seems to revolve around animal bones, in heaps, at around 20 sites. It is thought human depradation led to the extinction of megafauna, it would seem. Different papers vie to command the battlefield. The other major cause is climate change. No mention of catastrophism of course, even the creation of the heaps of bones. Cut marks are also defined as specific evidence. However, cut marks are distinctly difficult to prove and are often not what they seem. They are striations that could be caused by other factors such as bones being tossed around in turbuleant water.
