Green River Formation
25
This German lagerstätte dates back to the Jurassic period of the Mesozoic era, during the middle of the age of dinosaurs about 150 million years ago. This is where one of the first and most famous fossil birds was found, Archaeopteryx lithographica, which gave paleontologists new questions and answers regarding the origin of birds.
Solnhofen Limestone
26
This konservativ-lagerstätte, located in Illinois in the United States, can be divided mainly between marine and freshwater fauna, preserved together in what was thought to be an estuarine river delta. It is home to the truly bizarre animal Tullimonstrum (AKA Tully Monster) has been found, which is the state fossil of Illinois.
Mazon Creek
27
This lagerstätte is over 10 million years old than the famed Burgess Shale in Canada. It includes possibly over 100 species of soft-bodied animals, many of which their exact classification is still debated.
The Chengjiang biota
28
This lagerstätte is a 180 million-year-old German locality of Jurassic shale that has preserved a large variety of Jurassic period marine fauna. Disarticulated ichthyosaur remains are very common, such as scattered vertebrae, teeth, and other bones.
Posidonia Shale
29
Dating back to the Mississippian period of the Carboniferous, about 308 million years ago, _______ is a Montana lagerstätte which features an abundance of fish, aquatic arthropods, worms, microbial stromatolites, and molluscs. Chondrichthyans make up the majority of fish, and are remarkably diverse, with around 80 different genera attributed to the locale.
Bear Gulch
30
Many jawless fishes, primitive spiny sharks, and at least one lobe-finned fish have been recovered from this area. The site is also a wealth of invertebrate fossils, and notably, much like Beecher’s Trilobite Bed, there are many invertebrates such as brittle stars and trilobites found with extreme pyrite fossilization, giving them a look like tarnished gold.
Hunsrück Slate (Germany)
31
This is a Moroccan formation which dates back to the early Ordovician period, 480 million years ago. The fauna here fill a gap in the fossil record for a great many species, including some genera thought to have gone extinct at the end of the Cambrian period. Notable are the trilobites, including the Harpides, Asaphellus and Kierarges genera.
Fezouata Formation (Morocco)
32
Dating back to the Ordovician period of the Paleozoic era, the _________ is a wealth of trilobite fossils preserved in exquisite quality. The trilobite genera found here, such as Ceraurus, Flexicalymene, and Isotelus, even show fully fossilized appendages, the first trilobites to be discovered with preserved appendages.
Walcott-Rust Quarry
33
Located in Lebanon, these 100 million year old localities also show an abundance of smaller, soft-bodied marine organisms from the mid Cretaceous period. Astounding preservation has allowed animals like squid and octopodes to endure across the eons, and the preservation of genera like Keuppia and Styletoctopus paints a picture of the transition from ancestral squid-like forms to modern octopodes.
Hakel/Hjoula/Al-Nammoura
34
This succession of Middle Cambrian formations located in the House Range and Drum Mountains of Utah, is home to a lagerstätte of trilobites as well as a Burgess Shale-like soft-bodied fauna. Well over a 100 species of trilobites have been described from this mountain range, along with dozens of other marine critters including sponges, early echinoderms, enigmatic arthropods and even delicate jellyfish fossils.
Wheeler/Marjum/Weeks Formations
35
This is another konzentrat-lagerstätte which is, as the name suggests, very trilobite heavy. Charles Emerson Beecher discovered and named the location, but died unexpectedly in 1904, without passing on the exact location of the fossil bed. It was rediscovered in 1984 by Tom E. Whiteley (who also reopened the Walcott-Rust quarry for re-examination in 1990) and Dan Cooper, amateur fossil collectors.
Beecher’s Trilobite Bed (New York)
36
Located in the urban sprawl of Los Angeles, ________ offer a unique look into life during the Ice Age from 40,000 to 8,000 years ago. It contains possibly the richest, best preserved, and best studied assemblages of Pleistocene vertebrates, including at least 59 species of mammal, over 135 species of bird and over 600 species overall.
La Brea Tar Pits
37
Part of the larger Niobrara Chalk Formation, the ___________ lagerstätte dates to the Cretaceous period, over 86 million years ago. Located in Kansas, the site was, at the time, the shore of a wide but receding inland sea, and as such is home to a huge concentration of marine fossils. Reptiles like huge mosasaurs, some flighted pterosaurs, and turtles dominate the majority of faunal remains, and famously, a specimen of the monstrous fish Xiphactinus was once found here with another fish (Gillicus arcuatus) halfway down its throat!

95
This is an extinct species of sharks that appeared about 20 million years ago. They are considered not only the biggest shark but also the largest fish to have ever existed.
Megalodon/Otodus megalodon
96
The first fossils of this extinct herbivore were teeth and bones discovered in 1936 in Laya, Cagayan. They were identified as a new species based on features found in the premolars.
Nesorhinus philippinensis (formerly Rhinocerus philippinensis)
97
This is a giant species of pigs having distal enamel bands on its upper canines. It is believed that the pig’s ancestors arrived in the Philippines from Taiwan, and eventually migrated to the Indonesian island of Sulawesi. They are already extinct, and the geographical expansion of anoa (dwarf buffalo), babirusa (deer-pigs) and warty pig, which have produced competition, may have been the cause.
Celebochoerus cagayanensis
98
This is an even smaller water buffalo whose skeleton was discovered by accident by mining engineer Michael Armas more than 60 years ago while exploring for phosphate in a tunnel near the municipality of Balamban in island of Cebu. This species is an excellent example of island dwarfism in the family of Bovidae (buffalos, sheeps, goats, cows).
Cebu Tamaraw (Bubalus cebuensis)
99
As sediments pile up, fluids are squeezed out and the lower layers of sediments become more compressed, eventually turning to solid rock. Any plant parts contained within them are flattened.
