第一只 恐龙蛋 软蛋

在智利国家自然历史博物馆，有颗化石标本一直没被贴上分类标签，它于2011年被人从南极带回，长约28厘米，宽约18厘米，有点像泄了气的足球。过去近十年时间里，科学家对确认这颗化石的来历一直没什么头绪。无独有偶，美国自然历史博物馆的古生物学家马克·诺雷尔也有一个十几年都没解开的难题。2005年，他与同事在蒙古南部发现了一些原角龙蛋化石，这些蛋的内部有幼龙的骨骼雏形，但没人能解释为何蛋的边缘有一圈神秘的...

古代双足行走 恐龙 鳄鱼
2020/6/15
自然科研旗下《科学报告》杂志11日发表的一篇古生物学论文，韩国下白垩统晋州组发现了保存良好的较大足迹，这些足迹来自现代鳄鱼的祖先。研究指出，之前发现的曾被认为是双足行走的巨型翼龙的足迹，实际上可能是古代鳄鱼近亲留下的。此次，包括美国科罗拉多大学丹佛分校古生物学家在内的联合研究团队，在韩国泗川市附近的泗川自惠里遗址发掘过程中发现了多组足迹。研究人员将这些足迹取名为“Batrachopus grand...

据英国《自然》杂志近日发表的一篇论文，美国科学家发现了“超级大陆”的一具完整哺乳动物骨架。该骨架是冈瓦纳兽目的首个近乎完整的骨架，这项发现为理解早期哺乳动物的演化带来了线索。冈瓦纳的中生代（2.52亿—6500万年前）哺乳动物化石记录，远远不及北方超级大陆劳亚古大陆。冈瓦纳有一群哺乳动物被称为冈瓦纳兽目，它们是曾经生活在古代南方“超级大陆”的动物，以前人们只发现过它们零散的颌骨、牙齿和一块头骨。

南极洲 现存 蛙类 化石
2020/4/24
欧洲科学家团队报告在南极洲发现首个现存蛙类的化石，这一发现提供了进一步证据，证明了南极半岛在与南部超大陆（冈瓦纳大陆）分离之前拥有暖温带气候。新发现的化石属于“头盔蛙”科，这一化石的出现为人们带来了对古代南极的全新认识。相关研究报告23日发表在英国《科学报告》杂志上。
极端降雨或可诱发火山喷发
极端降雨 可诱发 火山喷发
2020/4/23
美国科学家团队在一项最新地球科学研究中称，极端降雨会激活深层岩浆运动，而发生在2018年的基拉韦厄火山喷发，可能就是由极端降雨触发的。这一发现表明在评估火山灾害时，应将降雨纳入考量范围。相关研究报告22日发表于英国《自然》杂志。
