Bucky
Size 33 × 11 ft (10 × 3.4 m)
Discovered Bucky Derflinger, 1998
Present location The Children's Museum of Indianapolis
Identification 2001.90.1 (furcula)

Bucky is a fossil of a juvenile Tyrannosaurus rex located in the Dinosphere exhibit in The Children's Museum of Indianapolis in Indianapolis, Indiana, United States.[note 1] It is the first juvenile Tyrannosaurus ever placed on permanent exhibit in a museum and was the first to be identified with a furcula.[2]

Description

Bucky has a bird-like skeletal structure, as it is one of the only dinosaur fossils found with a furcula.[3] A furcula, or fused clavicles, is a boomerang shaped "wishbone" that would measure 29 centimetres (11 in) wide and 14 centimetres (5.5 in) high. Bucky's furcula is the first one found for the genus Tyrannosaurus.[4] The furcula is thought to be a link between dinosaurs and birds and is the center of debate surrounding the origin of birds. Bucky also has a nearly complete set of gastralia, or belly ribs, and an ulna, or lower arm bone. As of now, 101 bones, or about 34% of Bucky's skeleton, has been discovered and verified.[5] Bucky is the sixth most complete Tyrannosaurus rex out of more than 40 that have been discovered.[2] Bucky's tail is the third most complete tail of any Tyrannosaurus rex known and has a nearly complete vertebral column to the end of the pelvis. Bucky's skull is a reconstruction which utilized modified casts of other Tyrannosaurus rex specimens.[6]

Display

Bucky is displayed in the Children's Museum of Indianapolis. Found in Dinosphere, Bucky is displayed along with Stan, an adult Tyrannosaurus, in a hunting scene. Both dinosaurs are attacking Kelsey the Triceratops. Bucky attacks Kelsey from behind, while Stan acts as a diversion in front of the triceratops. The end of the fight is left ambiguous. Bucky is displayed with a full set of gastralia, which is unusual. But because Bucky was discovered with a full set, it is displayed along with it.[7]

Discovery

The dinosaur remains were found in 1998 in the Hell Creek Formation near the town of Faith, South Dakota. The skeleton, transported by water, ended up in a low shallow valley along with bones from an Edmontosaurus and Triceratops. It was discovered by rancher and cowboy Bucky Derflinger. The excavation site was 150 by 30 feet (46 × 9.1 m), about 4,500 square feet (420 m2).[5] Bucky was well-preserved and easily prepared by the Black Hills Institute in South Dakota. Excavation and preparation of Bucky was relatively easy because the surrounding rock matrix was soft.[8]

Bucky Derflinger

Bucky Derflinger found Bucky's skeleton in 1998 when he was 20 years old. He was a rancher and a rodeo cowboy. While breaking in a young horse on his father's ranch, Derflinger discovered a pes phalange, or toe bone, from Bucky's skeleton. He has also discovered another Tyrannosaurus and a slew of remains of duck-billed dinosaurs on his father's land. Derflinger is the youngest person to discover a Tyrannosaurus. He has been collecting dinosaur fossils since he was nine years old.[9]

Notes

  1. ^ Some paleontologists suggest that female T.Rex were of the robust morphotype, which includes Bucky, but this method for distinguishing gender is not universally accepted.[1]
