Batyrosaurus is an extinct genus of theropod dinosaur that lived during the early Cretaceous period, approximately 135–128 million years ago. Its fossils were found in the Kuyezbaish Formation in the Russian Far East, making it the first theropod discovered in the region. Batyrosaurus was a medium-sized theropod, with an estimated length of 6.5-7 meters. Its remains indicate a relatively slender, lightly-built animal with a short neck and a long tail. Its skull was fairly short and deep, with a long snout, large, forward-facing eyes, and a deep lower jaw. Its teeth were long and curved, suggesting a carnivorous lifestyle.
The forelimbs of Batyrosaurus were relatively short, but the hind limbs were much longer, providing it with an upright, bipedal gait. Its hands had three fingers, and its feet had three toes - one of which was longer than the others and likely used for grasping prey. Unlike most other theropods, Batyrosaurus had a row of small, bony plates running along its back, neck, and tail. These plates were likely used for protection and may have also provided a form of camouflage. Despite its primitive features, Batyrosaurus was a fairly successful theropod, with numerous species known from the Early Cretaceous. It is believed to have been the ancestor of more advanced theropods such as Tyrannosaurus, which evolved later in the Cretaceous.

Batyrosaurus is an extinct genus of large, herbivorous dinosaurs closely related to Titanosaurs. The genus was first named and described in 2000 by paleontologists José Bonaparte and Rodolfo Coria.
It is known from a single species, Batyrosaurus rozhdestvenskyi, which lived during the Late Cretaceous period in what is now Argentina.
Batyrosaurus was a large, heavily-built dinosaur, estimated to have weighed up to 16 tons. It was approximately 20-25 meters long and 5-6 meters tall at the hips.
Its skull had a short, broad snout and was adorned with two large horns. Its body was covered in thick armor-like plates, and its tail was long and whip-like.
Batyrosaurus was a plant-eater, and its diet probably included ferns, cycads, and other low-growing vegetation. It probably lived in large herds and moved in slow, ponderous movements.
Comparisons between Batyrosaurus and other titanosaurs are difficult due to the scarcity of fossil remains. However, it can be distinguished from other titanosaur genera by its large horns, heavy armor, and whip-like tail.
The most closely related genus to Batyrosaurus is Rapetosaurus, which was discovered in Madagascar in 1997. Rapetosaurus was also a large, heavily-built dinosaur, but it lacked the horns and armor seen in Batyrosaurus.
Batyrosaurus is a genus of extinct large ornithopod dinosaurs that lived during the Late Cretaceous period. These dinosaurs were herbivores and were most likely found in what is now North America.
They are characterized by their large size and robust build, as well as their long, narrow skulls. These dinosaurs were up to 6.5 meters (21 ft) in length and weighed up to 2 tonnes (4,400 lb).
The first species of Batyrosaurus, B. grandis, was described in 1895 by Edward Drinker Cope. This species is known from a single incomplete skeleton from the Hell Creek Formation in Montana.
This species may have been up to 8 meters (26 ft) long, making it one of the largest ornithopods known.
The second species, B. laticostalis, was described in 1915 by Charles W. Gilmore. This species is known from a single incomplete skeleton from the Lance Formation in Wyoming.
This species was smaller than B. grandis, measuring up to 6.5 meters (21 ft) in length.
The third species, B. robustus, was described in 1933 by Charles W. Gilmore. This species is known from a single incomplete skeleton from the Scollard Formation in Alberta, Canada.
This species was slightly smaller than B. laticostalis, measuring up to 6 meters (19.7 ft) in length.
The fourth species, B. browni, was described in 1985 by John Ostrom and David B. Weishampel. This species is known from a single incomplete skeleton from the Judith River Formation in Montana.
This species was slightly smaller than B. robustus, measuring up to 5.5 meters (18 ft) in length.
Batyrosaurus is one of the best-known ornithopods of the Late Cretaceous. These dinosaurs were large, robust, and had long, narrow skulls.
They are believed to have been herbivorous, and may have lived in herds. While their fossils are rare, they provide valuable insights into the diversity of Late Cretaceous ornithopods.
