This suggests that dietary adaptations were an important driver during the evolution of theropod dinosaurs and their transition to modern birds. The Giant Claw: A Walking with Dinosaurs Special. This new study reveals that, during this transition, theropod dinosaurs developed a large variety of claw shapes adapted to specific functions, such as digging, grasping or piercing.Дr Lautenschlager said: 'ItвЂ™s fascinating to see that, with the shift from a carnivorous to a plant-based diet, we find a large variety of claw shapes adapted to different functions. in an Early Cretaceous Mongolia to find the dinosaur with the largest claws: Therizinosaurus. In the course of evolution, several theropod groups, including therizinosaurs, changed from being carnivores to become plant-eaters. The dinosaur claws were also compared to the claws of mammals, still alive today, whose function (that is, how and for what the claws are used) is already known. In order to fully understand how these different claws on the forelimbs were used, detailed computer models were created to simulate a variety of possible functions for different species and claw morphologies. This two-part series, a sequel to Walking with Dinosaurs featured Nigel and his 'team of fellow explorers' encountering prehistoric life over a large range of time, and seeing creatures not featured in the original series. This allowed them to develop a whole new suite of claw shapes adapted to different functions.' HORSESHOE CRAB FRILL SHARK ALLIGATORS CROCODILES NAUTILUS COELACANTH STURGEON DRAGONFLY Imagining that dinosaurs are still walking the planet is very. But in spite of their bizarre appearance, therizinosaurs were peaceful herbivores.Дr Lautenschlager said: 'Theropod dinosaurs were all bipedal, which means their forelimbs were no longer involved in walking as in other dinosaurs. Therizinosaurs were very large animals, up to 7m tall, with claws more than 50cm long on their forelimbs, elongated necks and a coat of primitive, down-like feathers along their bodies. His research focussed on the therizinosaurs, an unusual group of theropods which lived between 145 and 66 million years ago. Therizinosaurus was featured in a Walking With Dinosaurs Special - Chased By Dinosaurs, where it was referred to as Claws.

Inspired by this broad spectrum of claw morphologies, Dr Stephan Lautenschlager from Bristol's School of Earth Sciences studied the differences in claw shape and how these are related to different functions.

However, a detailed look at the claws on their forelimbs revealed that the form and shape of theropod claws are highly variable and might also have been used for other tasks. Indeed, the second episode of CBD, The Giant Claw, was centered on the Therizinosaurus, as Nigel Marvin theoretized as to what sort of creature it could be. Theropod dinosaurs, a group which includes such famous species as Tyrannosaurus rex and Velociraptor, are often regarded as carnivorous and predatory animals, using their sharp teeth and claws to capture and dispatch prey. Like many theropod dinosaurs, Therizinosaurus may have been theoretically feathered, but Chased by Dinosaurs (2003) has shown it to be featherless instead.
