Georges Cuvier came to believe that most if not all the animal fossils he examined were remains of extinct species. This led Cuvier to become an active proponent of the geological school of thought called catastrophism. Near the end of his 1796 paper on living and fossil elephants he said: From the 13th century to the present day, scholars pointed out that the fossil skulls of Deinotherium giganteum, found in Crete and Greece, might have been interpreted as being the skulls of the Cyclopes of Greek mythology, and are possibly the origin of that Greek myth. [86] [87] Their skulls appear to have a single eye-hole in the front, just like their modern elephant cousins, though in fact it's actually the opening for their trunk.

This is a special form of cast and mold formation. If the chemistry is right, the organism (or fragment of organism) can act as a nucleus for the precipitation of minerals such as siderite, resulting in a nodule forming around it. If this happens rapidly before significant decay to the organic tissue, very fine three-dimensional morphological detail can be preserved. Nodules from the Carboniferous Mazon Creek fossil beds of Illinois, US, are among the best documented examples of such mineralization. [18] Replacement and recrystallization Silicified (replaced with silica) fossils from the Road Canyon Formation (Middle Permian of Texas) Recrystallized scleractinian coral (aragonite to calcite) from the Jurassic of southern Israel Roman naturalist Pliny the Elder wrote of " tongue stones", which he called glossopetra. These were fossil shark teeth, thought by some classical cultures to look like the tongues of people or snakes. [74] He also wrote about the horns of Ammon, which are fossil ammonites, from whence the group of shelled octopus-cousins ultimately draws its modern name. Pliny also makes one of the earlier known references to toadstones, thought until the 18th century to be a magical cure for poison originating in the heads of toads, but which are fossil teeth from Lepidotes, a Cretaceous ray-finned fish.

The fossil she was most fascinated with, though, was the coprolite, which—as the guide states—is “fossilized animal poop.” My child dissolved into giggles once she realized she’d found fossilized animal scat. She couldn’t wait to show it to her sisters.The fossil record is life's evolutionary epic that unfolded over fourbillion years as environmental conditions and genetic potential interacted in accordance with natural selection.

Despite significant advances in uncovering and identifying paleontological specimens, it is generally accepted that the fossil record is vastly incomplete. [103] [104] Approaches for measuring the completeness of the fossil record have been developed for numerous subsets of species, including those grouped taxonomically, [105] [106] temporally, [107] environmentally/geographically, [108] or in sum. [109] [110] This encompasses the subfield of taphonomy and the study of biases in the paleontological record. [111] [112] [113] ArtCyclops Myth Spurred by 'One-Eyed' Fossils?".
