The Green River Formation in Wyoming represents one of the largest and most important documented accumulations of sedimentary rocks in the world and dates from approximately 50 million years ago. It covers an area of more than 25,000 square miles and has an average of 6,000 meters thick. These lakes were formed by geological changes that elevated the Rocky Mountains in the early times. The climate was very different from the current desert climate, it was identical to the existing current subtropical climate of the Gulf Coast and the areas of the South Atlantic of the United States currently. Notogoneus osculus (osculus from the Latin 'mouth') was an opportunist spending most of its life in rivers that are connected and fed on flow to the inland lake only went into the Lake during certain seasons when when the bottom waters were nontoxic. As a result of this circumstance Notogoneus is uncommon and rare in the Green River formation. The usual size of this genus is around 18 inches (45.7 cm) and its maximum length is 3 feet (91 cm) small specimens are extremely rare. Notogoneus was a predatory creature and would have powered creatures at or near the bottom of its habitat, probably at night Notogoneus fed mainly on crustaceans. You could say that has certain similarities with a fish current modern suction cup. Genuine and original authentic fossil, giant fossil fish, plate prepared by professionals in the quarry of origin, mounted and reinforced on a wooden base for better exposure and protection, completely natural piece, no restoration , no repair, complete fish, out of size , measures plate-slab: 590 x 350 x 25 mm , measures fish : 450 x 95 mm (approximate measurements), weight: 8.700 grams, excellent museum quality, veryrare , collector's choice , gorgeous.

Age: Campanian( about 72 -83 million years)
Common name: fossil hadrosaur egg, "bulky lizards",duck-billed
Comments: this wonder is a nest with three complete fossilized eggs of the genus hadrosaur (dinosaur) meaning "bulky lizards". Most deposited their eggs in nests to put up a dozen or more. With hatching and compaction usually damaging nests, erasing any trace of the eggs. Occasionally, some eggs survived predators and the weather elements and eventually became fossils. Due to their fragility and delicate nature intact eggs are very difficult and rare in the fossil record. Dinosaur eggs which preserved the egg shell and its original characteristic form are some of the fossils more sought after and desired by collectors around the world. Extint, dinosaur, herbivorous, ornithopods, chewing plants, Hadrosaurus was able to use his limbs (front legs) for standing and feed, famous for being one of the dinosaurs cloned on the novel by Michael Crichton, Jurassic Park. Nest with three eggs very well preserved and in its original matrix, totally natural, authentic and genuine fossil , not mounted, without restoration, repair, caulk or paint, original and authentic fossil, complete shell, very scarce and difficult today, the process of export of Chinese fossils is currently paralyzed legal piece from old collection imported in the past, comes with certificate of authenticity, in very good condition, measures eggs : 110 x 100 mms , 93 x 103 mm and 110 x 99 mm approximately, measures matrix : 315 x 210 x 85 mms, weigth : 10.400 grams, museum quality, excellent quality, from old collection, worthy of a museum , gorgeous.

Procedente de los legendarios yacimientos de la formación Green River en Wyoming cuyos fósiles son muy valorados por su variedad , gran calidad y conservación, además de peces , otros invertebrados y plantas se han localizado en esta formación excelentemente conservados , según los científicos este magnífico estado de conservación único en el mundo, es debido a la combinación de dos circunstancias : primero un período de frío intenso durante el Eoceno que habría causado que los peces sin vida se hubiesen hundido más rápido debido a que su vejiga natatoria se habría hinchado menos y segundo la gran profundidad de los lagos y las condiciones excepcionales de falta de oxígeno en el agua , esto habría impedido que los animales carroñeros destruyeran los cadáveres. Diplomystus es un género extinto de pez del Eoceno extraordinariamente bonito por su original morfología y la estructura característica y forma única de su boca . Los fósiles de este pez se encuentran fosilizados comúnmente en esta área, junto con otros géneros de interés como Knigtia, Priscacara, Mioplosus, Phaerodus, Notogoneus . Su hábitat, con toda probabilidad fueron los lagos y corrientes de agua dulce de la Formación Green River, se alimentaban de pequeños organismos , bivalvos , otros peces y se desplazaban habitualmente en solitario . Mioplosus labracoides es un pez extinto con un cuerpo largo y fuerte similar en apariencia a una perca(carpa) actual. Según los restos fósiles encontrados tenía unos dientes puntiagudos que demuestran que era un depredador voraz y letal. Con frecuencia comía otros peces con un tamaño de hasta la mitad de su propia longitud, que le producían la muerte por asfixia , se han encontrado muchas placas con restos fósiles de ejemplares completos que lo demuestran , El Mioplosus moría mientras intentaba comer su cena. Mioplosus es una de las especies más raras y buscadas de Green River FM. ( Filo : Chordata, Subfilo: Vertebrata, Infrafilo: Gnathostomata, Superclase: Osteichthyes, Clase: Actinopterygii.

Description: fossil fish, giant predator
Period: Paleogene
Epoch-Stage-Strata: Lower Eocene
Era: Cenozoic
Age: Ypresian (about 47-56 million years)
Common name: fossil fish , giant predator, prehistoric fossil fish
Comments: Kingdom: Animalia, Phylum: Chordata, Class: Actinopterygii, Order: Gonorynchiformes, Family: Gonorynchidae, Genus: Notogoneus. Extint. The legendary sites of the formation from Green River in Wyoming whose fossils are very valued by its variety, high quality,and conservation,as well as fish,other invertebrates and plants have been located in this excellently preserved, according to scientific training this magnificent state of conservation in the world, it is due to a combination of two factors : first a period of cold deep during the Eocene, which would have caused that lifeless fish had sunk faster since its swim bladder would have inflated less and second the great depth of the lakes and the exceptional conditions of lack of oxygen in the water, this would have prevented scavengers animals destroyed the corpses . Notogoneus osculus (osculus from the Latin 'mouth') was an opportunist spending most of its life in rivers that are connected and fed on flow to the inland lake only went into the Lake during certain seasons when when the bottom waters were nontoxic. As a result of this circumstance Notogoneus is uncommon and rare in the Green River formation. The usual size of this genus is around 18 inches (45.7 cm) and its maximum length is 3 feet (91 cm) small specimens are extremely rare. Notogoneus was a predatory creature and would have powered creatures at or near the bottom of its habitat, probably at night Notogoneus fed mainly on crustaceans. You could say that has certain similarities with a fish current modern suction cup.

Common name: fossil fish , giant predator, prehistoric fossil fish
Comments: Kingdom: Animalia, Phylum: Chordata, Subphylum: Vertebrata, Infraphylum: Gnathostomata, Superclass: Osteichthyes, Class: Actinopterygii, Order: Osteoglossiformes, Family:Osteoglossidae, Genus: Phareodus. Extint. The legendary sites of the formation from Green River in Wyoming whose fossils are very valued by its variety, high quality,and conservation,as well as fish,other invertebrates and plants have been located in this excellently preserved, according to scientific training this magnificent state of conservation in the world, it is due to a combination of two factors : first a period of cold deep during the Eocene, which would have caused that lifeless fish had sunk faster since its swim bladder would have inflated less and second the great depth of the lakes and the exceptional conditions of lack of oxygen in the water, this would have prevented scavengers animals destroyed the corpses . The Green River Formation in Wyoming represents one of the largest and most important documented accumulations of sedimentary rocks in the world and dates from approximately 50 million years ago. It covers an area of more than 25,000 square miles and has an average of 6,000 meters thick. These lakes were formed by geological changes that elevated the Rocky Mountains in the early times. The climate was very different from the current desert climate, it was identical to the existing current subtropical climate of the Gulf Coast and the areas of the South Atlantic of the United States currently. Phareodus encaustus is easily distinguished by its long pectoral fin (prominently displayed in this specimen) and its large pointed teeth. The teeth are a characteristic of the probable carnivorous behavior of these predatory fish and also the remains of scales that are often preserved in the stomachs of the fossil remains found. The name means "to have a tooth". The Phaerodus member of the Osteoglossidae family, has existing cousins found in Central America, South America and Southeast Asia. This is really an amazing specimen because of its and magnificent preservation. Phaerodus was a predatory creature and is common in the formation of Green River in both adult and juvenile specimens. Genuine authentic and original fossil , completely natural piece, giant fossil fish with all its organism, fins, tail and head intact, perfectly preserved and fossilized, without restoration or repair, the sample is prepared by professionals in the quarry of origin, the plate is presented reinforced and mounted on a wooden base for better consolidation, safety, transport and exhibition, repaired and consolidated in the corners of upper and lower right with a special solid and compact material, individual of extraordinary size, top size for the species, giant fossil fish, measures plate-slab : 660 x 560 x 20 mm(26 x 22 x 0.79 inches), approximate fish measures: 590 x 250 mm(23 x 9.5 inches), weight: 10,700 grams, one of the star fish most sought by collectors for its spectacular and primitive and pre-historic aspect of the fauna of Green River .
