Using archaeologists data, engineers recreated a lizard gait – ancestor of modern mammals.
Researchers from the Berlin University named after Gumboldt and the Swiss Higher Technical School Zurich created a robot on the basis of a skeleton of an animal existing before dinosaurs. Applying a technology complex, they put him a gait of ancient reptile. Work is published in the Nature magazine.
ORABATES PABSTI fossils found in the career of Bromacher (Germany) in 2000. This creature was interested in scientists primarily because of their position on the tree of evolution. They believe that it is one of the first ancient amnimists – vertebrates, characterized by the presence of germinal shells. Mammals developed out of it. According to scientists, the first amniotes appeared 310 million years ago. The age of used in the work of the skeleton is estimated at 290 million years.
To recreate gait, the authors could not count only on the remaining bones. They used petrified traces that belonged to ORABATES PABSTI with a body length of 90 centimeters. In addition, they studied existing lizards using computed tomography to assess their gait. To create a model of movements, researchers of the University of Berlin appealed to the staff of the Swiss Higher Technical School Zurich.

Specialists have created accurate bone replicas with dimensions one to one, but later when assembling the robot orobot slightly increased their scale. All other parts were printed on a 3D printer, taking into account the alleged mass of the animal.
After all the work done, scientists concluded that ORABATES PABSTI had a more advanced way of movement than previously thought. According to them, the lizards rather ran out than they slid over the surface, which speaks of their ability to move away from the water further than expected. This method of modeling allowed the authors to learn more about the details of the movement of an ancient creature, so they hope to apply the same approach in the future to other animals, such as dinosaurs.

Prior to this, Paleontologists were for the first time to explore almost a meter skull of a giant ichthyosis, found more than 60 years ago. Using advanced computer tomography technologies, researchers have created a 3D model of the remains, including the details of the skull, which are quite rarely persistent in nature.
