FA?ssil ai???perfeitoai??? de pA?ssaro com 99 milhAi??es de anos Ai?? encontrado

A descoberta do fA?ssil de milhAi??es de anos em boas condiAi??Ai??es ajudarA? cientistas a entender evoluAi??A?o de aves

Nos A?ltimos anos, um depA?sito gigantesco de A?mbar em Myanmar proveu um verdadeiro baA? de tesouros para pesquisadores deAi??animaisAi??antigos, presos na resina fossilizada. Agora, os cientistas encontraram o fA?ssil mais bem conservado de um pA?ssaro em A?mbar, conforme reportou aAi??National Geographic.

O pA?ssaro, que ficou preso no material ainda bebA?, tem 99 milhAi??es de anos e viveu no final do perAi??odo CretA?ceo. De acordo com oAi??Science Bulletin, ele mede 6 centAi??metros. O exterior do pA?ssaro Ai?? estranhamente transparente, permitindo que os pesquisadores observem a parte interna de seu corpo, que incluiu a parte traseira do crA?nio, pedaAi??os de uma asa, uma pata, a maior parte da coluna e os quadris.

De acordo com o que o time de cientistas pode analisar da descoberta, a criatura acabou caindo na resina ai??i?? mas nA?o Ai?? possAi??vel saber se, no momento em que isso aconteceu, ele estava vivo ou morto. Com o tempo, parte do tecido e ossos se decompuseram, dando lugar a outros sedimentos.

Julia Clark, especialista em evoluAi??A?o de pA?ssaros da Universidade do Texas, falou Ai??Ai??National GeographicAi??sobre a descoberta. ai???Este depA?sito de fA?sseis chegou para mudar o jogo. Ai??, sem sombra de dA?vidas, a descoberta mais importante para entender a evoluAi??A?o de pA?ssaros na atualidadeai???, afirmou.
