Fossils of extinct species from our planet’s ancient past are still being uncovered around the world. Researchers working in the Caiuá desert of Brazil have published a study about their discovery of remains of pterosaurs, a new species of ancient flying reptile, closely related to dinosaurs. Fossils of extinct species from our planet’s ancient past are still being uncovered around the world. Researchers working in the Caiuá desert of Brazil have published a study outlining their discovery of pterosaur remains, a new species of ancient flying reptile, closely related to dinosaurs. Fossils of more than 47 specimens have been recovered from the thousands of bones in an old lake deposit near the city of Cruzeiro do Oeste located in the southern state of Parana, Brazil. According to the fossil evidence, the pterosaurs had a wingspan of between two point one and seven point seven feet. Among the remains were adult and juvenile pterosaurs, so experts were able to learn more about the reptiles that lived around 75 to 87 million years ago. Authors of the study detailing the discovery wrote: “The presence of three main levels of accumulation in a section of less than one meter suggests that this region was home to pterosaur populations for an extended period of time.” Other pterosaur traits that are described by the study include the possibility that they were social animals that learned to fly at a young age.
灭绝的物种从地球上的远古化石仍然被揭露了世界各地。研究人员在巴西Caiuá沙漠工作已经发表了他们的发现遗体翼龙的研究，古代爬行动物飞行的一个新种，密切相关的恐龙。 灭绝的物种从地球上的远古化石仍然被揭露了世界各地。 研究人员在巴西Caiuá沙漠工作已发表的一项研究，概述了他们的发现翼龙遗迹，古老的爬行动物飞行的一个新种，密切相关的恐龙。 超过47的化石标本已被追回，从数千骨头在老湖沉积物市附近的克鲁赛罗做伊斯特位于巴西巴拉那州南部。 根据化石证据，翼龙有脚之间的两个点之一，七点七的翼展。 在遗体被成年和少年翼龙，因此专家们能够更多地了解了生活在大约75至87万年前的爬行动物。 这项研究详细介绍了发现的作者写道：“积累的三个主要层次少于一米一节的存在表明，该地区是家庭对翼龙的人口为长一段时间。” 这是由研究中所描述的其他翼龙特征包括的可能性，他们认为学会了在年轻的时候飞群居动物。
