A very interesting article and the theme of dinosaurs is very interesting to me. T-rex is a clear representative of the Cretaceous periud and for his time he was a formidable force. He really is the most impressive predator in the history of our planet. Its name comes from two ancient Greek words: a tyrant, a tyrant. By the size of the body is now the second terrestrial predator, yielding the palm of leadership to only the spinoza. However, for all other parameters, including the general musculature and massiveness of the head, he is superior to the latter. Thank you @gavvet
