Sotheby’s: GORGOSAURUS SKELETON

ESQUELETO DE GORGOSAURIO

Especificaciones de Gorgosaurus.

Cretácico superior (hace aproximadamente 77 millones de años)

Formación del río Judith, condado de Choteau, Montana

Esqueleto montado listo para exhibición, que mide 9 pies, 2½ pulgadas de alto (110,5 pulgadas, 113,5 con armadura), poco menos de 22 pies de largo (263,5 pulgadas). Cráneo que mide 38½ por 26½ por 17 pulgadas (97,8 x 67,3 x 43,2 cm). 79 elementos fósiles, montados en una armadura personalizada con elementos fundidos adicionales.

El Gorgosaurus vagaba por la Tierra hace unos 77 millones de años, aproximadamente 10 millones de años antes de que su pariente más famoso, el T-Rex. Bien conservado hasta que fue descubierto en 2018 en la formación del río Judith de Montana, este espécimen en particular es un gran ejemplo de este depredador ápice.

Con una altura aproximada de 10 pies y 22 pies de largo, es uno de los pocos encontrados en los EE. UU., y el único ejemplo conocido que no está en un museo o una gran colección. Se subastará como parte de la venta de Historia Natural de Sotheby’s en Nueva York el 28 de julio y se espera que se venda por hasta $ 8 millones.

EL PRIMER ESPECIMEN DE SU TIPO EN SUBASTAR, UNO DE LOS ÚNICOS 20 EJEMPLOS CONOCIDOS, Y EL ÚNICO QUE SE CONOCE QUE ESTÁ DISPONIBLE PARA PROPIEDAD PRIVADA

A DIFERENCIA DE OTROS ESQUELETOS DE DINOSAURIOS QUE HAN LLEGADO RECIENTEMENTE AL MERCADO, A ESTE ESPECIMEN AÚN NO SE LE HA DADO UN APODO: EL NUEVO PROPIETARIO PODRÁ ELEGIR EL NOMBRE DE SU ELECCIÓN

Gorgosaurus  era un dinosaurio depredador cuyo nombre significa “lagarto temible”. Era un carnívoro ápice bípedo que vivió hace aproximadamente 76 millones de años en lo que ahora es el oeste de América del Norte.

Se cree que  el cuerpo de Gorgosaurus  alcanzó una longitud de casi 30 pies y pesó alrededor de tres toneladas, y los paleontólogos han podido hacer representaciones educadas de la forma de su cuerpo basándose en la pequeña cantidad de restos óseos fósiles que se han descubierto así. lejos. Lo que podemos ver es que al final de un enorme cuello en forma de S, se sostenía una enorme cabeza que albergaba docenas de dientes largos, delgados y aserrados de doble filo.

La dentición en la parte frontal del hocico tenía forma de D, y la parte posterior de las mandíbulas parecía ovalada en sección transversal, que estaban diseñadas idealmente para perforar y cortar. Las proporciones de sus patas eran más típicas de los dinosaurios bípedos de rápido movimiento, y su larga cola actuaba como contrapeso mientras corría. Los paleontólogos especulan que  Gorgosaurus  podría haber usado estas adaptaciones para cazar herbívoros contemporáneos, incluidos los hadrosaurios  Lambeosaurus  y  Corythosaurus , los ceratopsianos  Styracosaurus  y  Centrosaurus , y los anquilosaurios acorazados  Edmontonia  y  Euplocephalus .

El registro fósil indica que  Gorgosaurus coexistió con el terópodo Daspletosaurus ,  de distribución menos amplia pero de tamaño similar  , con quien compitieron por los recursos. Ambos eran miembros de la familia Tyrannosauridae, que incluye superdepredadores norteamericanos y asiáticos como  Tyrannosaurus ,  Tarbosaurus ,  Albertosaurus ,  Daspletosaurus y otros. El propio Gorgosaurus  es anterior al  Tyrannosaurus rex  en unos 10 millones de años. Se les considera una especie prima del  Tyrannosaurus rex , y una pieza crucial en la comprensión de la diversidad evolutiva de toda la familia Tyrannosaurid.

Imágenes de condiciones y detalles

Los huesos se conservan con exquisito detalle, mostrando poca distorsión y conservando gran parte de su forma original y características de la superficie. En general, la fosilización de este  Gorgosaurus  es magnífica. La pátina es de un marrón claro a medio, un color consistente con la mayoría de los fósiles de vertebrados de la Formación Judith River. No hay signos de “enfermedad de pirita” u otros problemas minerales que representen un problema con la preservación futura de los fósiles.

El cráneo está representado por un maxilar izquierdo bellamente conservado y una variedad de huesos craneales. El lado izquierdo del cráneo está bien representado, incluido el maxilar conservado y los tres huesos principales que crean la órbita redondeada. La forma de la órbita es una característica distintiva entre  Gorgosaurus  y  Tyrannosaurus . El maxilar incluye dos dientes expuestos completamente enraizados, tres dientes parciales y cinco dientes no erupcionados en sus alvéolos. El maxilar, en general, muestra muy poca distorsión y es grande en comparación con otros   maxilares de Gorgosaurus .

El  espécimen de Gorgosaurus  contiene un esqueleto axial bien documentado con material que representa las vértebras cervicales, dorsales y caudales. El esqueleto axial también incluye una pelvis excepcionalmente bien conservada, con los once elementos representados, incluidos los huesos del pubis articulados completos.

Sotheby’s: GORGOSAURUS SKELETON

GORGOSAURUS SKELETON

Gorgosaurus spec.

Late Cretaceous (approx. 77 million years ago)

Judith River Formation, Choteau County, Montana

Exhibition-ready mounted skeleton, measuring 9 feet, 2½ inches tall (110.5 inches, 113.5 with armature), just under 22 feet long (263.5 inches). Skull measuring 38½ by 26½ by 17 inches (97.8 x 67.3 x 43.2 cm). 79 fossil elements, mounted on custom armature with additional cast elements.

The Gorgosaurus roamed the Earth about 77 million years ago, roughly 10 million years before it’s more famous relative, the T-Rex. Well-preserved until it was discovered in 2018 at Montana’s Judith River Formation, this particular specimen is a great example of this apex predator.

Standing around 10 feet tall and 22 feet long, it’s one of one a few ever found in the US, and the only known example not in a museum or large collection. It’s going up for auction as part of Sotheby’s Natural History sale in New York on July 28, and is expected to sell for up to $8 million.

THE FIRST SPECIMEN OF ITS KIND TO COME TO AUCTION —ONE OF ONLY ABOUT 20 KNOWN EXAMPLES, AND THE ONLY KNOWN TO BE AVAILABLE FOR PRIVATE OWNERSHIP

UNLIKE OTHER DINOSAURS SKELETONS THAT HAVE RECENTLY COME TO MARKET, THIS SPECIMEN HAS NOT YET BEEN GIVEN A NICKNAME — THE NEW OWNER WILL GET TO PICK THE NAME OF THEIR CHOICE

Gorgosaurus was a predatory dinosaur whose name means “dreadful lizard”. It was a bipedal, apex carnivore that lived approximately 76 million years ago in what is now western North America.

It is believed that Gorgosaurus’ body reached lengths of nearly 30 feet and weighed in at around three tons, and paleontologists have been able to make educated depictions of its body-shape based on the very small number of fossil skeletal remains that have been discovered thus far. What we can see is that at the end of a massive S-shaped neck, a huge head was held that housed dozens of long, slim, double-edged serrated teeth.

The dentition in the front of the snout were D-shaped, and those in the rear of the jaws appearing oval in cross section, which were ideally designed for piercing and cutting. Its leg proportions were more typical of swift-moving biped dinosaurs, and its long tail acted as a counterbalance while running. Paleontologists speculate that Gorgosaurus might have used these adaptations to hunt herbivorous contemporaries including the hadrosaurs Lambeosaurus and Corythosaurus, the ceratopsians Styracosaurus and Centrosaurus, and the armored ankylosaurs Edmontonia and Euplocephalus.

The fossil record indicates that Gorgosaurus coexisted with the less-widely distributed but similarly-sized theropod, Daspletosaurus, with whom they competed for resources. Both were members of the family Tyrannosauridae, which includes both North American and Asian super predators such as TyrannosaurusTarbosaurusAlbertosaurusDaspletosaurus, and others. Gorgosaurus itself predates Tyrannosaurus rex by about 10 million years. They are considered a cousin species to Tyrannosaurus rex, and a crucial piece in the understanding of the evolutionary diversity of the entire Tyrannosaurid family.

Condition & Detail Images

The bones are preserved in exquisite detail, exhibiting little distortion and retaining much of their original shape and surface characteristics. Overall, the fossilization of this Gorgosaurus is superb. The patina is a light to medium brown, a color consistent with most vertebrate fossils from the Judith River Formation. There is no sign of “pyrite disease” or other mineral issues that would represent a problem with future preservation of the fossils.

The skull is represented by a beautifully preserved left maxilla and an assortment of cranial bones. The left side of the skull is well represented including the preserved maxilla and the three major bones that create the rounded orbit. The shape of orbit is a distinguishing feature between Gorgosaurus and Tyrannosaurus. The maxilla includes two fully rooted exposed teeth, three partial teeth, and five unerupted teeth in their alveoli. The maxilla, overall, shows very little distortion and is large as compared to other Gorgosaurus maxillae.

The Gorgosaurus specimen contains a well-documented axial skeleton with material representing the cervical, dorsal, and caudal vertebrae. The axial skeleton also includes an exceptionally well-preserved pelvis, with all eleven elements represented including complete articulated pubis bones.
