No trabalho, pesquisadores recriaram digitalmente uma trilha de pegadas de dinossauro de 120 milhões de anos

Um entendimento que pode mudar a partir de um novo estudo publicado na revista Geosciences . Neste trabalho, os pesquisadores da Universidade de Queensland, na Austrália, recriaram digitalmente uma trilha de pegadas de 120 milhões de anos.
Pegadas cobriram quase 70 metros de distância 652x31 As marcas foram encontradas na vila de Hanxi, na atual China, no que é considerada a trilha mais longa deixada por um terópode no leste asiático. No total, são 81 pegadas consecutivas e que cobrem quase 70 metros de distância. Estes rastros são fundamentais para o estudo dos dinossauros. No entanto, são difíceis de se decifrar por conta dos desafios logísticos de medir as pegadas no ambiente. Para superar este desafio, os cientistas resolverem recriar a trilha em um computador. O resultado deste trabalho ajudou a equipe a revelar detalhes do comportamento destes animais extintos. Veja o resultado no vídeo abaixo:
Revelações sobre o comportamento do animal 6i272f A partir da recriação digital das pegadas, os pesquisadores conseguiram analisar os os dos dinossauros em detalhes. Foi possível perceber, por exemplo, mudanças de ritmo e até respostas ao ambiente.
Segundo os cientistas, as marcas revelaram que o animal acelerou de forma breve durante a trilha antes de voltar ao ritmo normal. Toda a movimentação dele foi feita quase que em uma linha perfeitamente reta.

O animal se movia a 5,3 km/h, o equivalente a um humano andando rapidamente. Estas informações podem sugerir que o espécime era um Yutyrannus, espécie que viveu na região no início do Período Cretáceo.
