In dinosaur news this week: The newly named Tameryraptor is such a significant find that it could be considered the original Carcharodontosaurus This week's dinosaur of the day is Dakotadon Iguanodont that lived in the Early Cretaceous in what is now South Dakota, U.S. (Lakota Formation) Looked similar to Iguanodon. Could walk on all fours, had a bulky body, a long tail, and an elongated head Estimated to be about 20 ft (6 m) long and weigh 1 metric ton Described in 1989 by David Weishampel and Philip Bjork, but was described as Iguanodon lakotaensis Species name refers to "the land of the Lakota and the horizon from which the type specimen was collected" Found a partial skull and parts of the skeleton Louis Rossow had found the fossils when hunting rattlesnakes on a hogback (long narrow ridge or series of hills) near Sturgis, and excavated them with the help of us family. Dale Rossow, Louis Rossow's son, told John Willard from the South Dakota School of Mines and Technology about them Louis Rossow had been storing the fossils in his garage (fossils donated to the Museum of Geology) Debated about where it fit in.

Also said it was "the first indisputable record of Iguanodon from North America" Described the nearly complete skull, part of the lower jaws, and two vertebrae (one from the neck and one from the tail) Skull described as oblong (long, oval) Considered to be Iguanodon because of the proportions of its face, the way its beak looked, the patterns of the teeth, as well as other patterns on the bones However, this species was larger than Iguanodon atherfieldensis, and it also had fewer teeth and a few other minor differences compared to the European species Gregory Paul renamed it Dakotadon in 2008 … read more at https://iknowdino.com/Dakotadon-Episo...
