江西發(fā)現(xiàn)全球最小恐龍蛋化石 被命名為“贛州迷你蛋”

來源:大江網(wǎng)-江西日報

本報贛州訊 (全媒體記者童夢寧)10月16日,記者從贛州市相關(guān)單位獲悉,近日,專業(yè)學(xué)術(shù)國際期刊《歷史生物學(xué)》發(fā)布了有關(guān)贛州盆地白堊紀(jì)晚期恐龍蛋研究的最新成果:古生物科研人員歷時近三年科研攻關(guān),確認(rèn)贛州市贛縣區(qū)梅林鎮(zhèn)境內(nèi)新發(fā)現(xiàn)的一窩小型恐龍蛋化石是全新的蛋種,其中6枚恐龍蛋化石無規(guī)則排列,呈橢圓形,長軸僅2.9厘米,個頭比鵪鶉蛋(常規(guī))還小,刷新已知的世界最小恐龍蛋紀(jì)錄,被命名為“贛州迷你蛋”,為當(dāng)前全球保存完整且有記錄的最小恐龍蛋化石。

恐龍蛋作為恐龍繁殖的重要產(chǎn)物,對恐龍的繁衍及其生存環(huán)境研究至關(guān)重要。第四屆國家古生物化石專家委員會委員、江西省地質(zhì)調(diào)查勘查院總工程師樓法生介紹,“贛州迷你蛋”的特征說明遠古時期江西境內(nèi)出現(xiàn)過一種未知的小型獸腳類恐龍,進一步增進了古生物研究領(lǐng)域?qū)M州盆地白堊紀(jì)晚期恐龍多樣性的了解,對恐龍到鳥類的行為方式等演化過程、白堊紀(jì)古生態(tài)和古環(huán)境恢復(fù)等方面研究,均起到十分關(guān)鍵作用。

據(jù)了解,2021年9月起,科研人員開始著手在梅林鎮(zhèn)境內(nèi)搶救性發(fā)掘這6枚迷你型恐龍蛋。同時,在國家自然科學(xué)基金委員會的大力支持下,江西省地質(zhì)調(diào)查勘查院、中國地質(zhì)大學(xué)(武漢)、中國科學(xué)院古脊椎動物與古人類研究所、江西省地質(zhì)博物館共同成立科研團隊,進行聯(lián)合攻關(guān),最終實現(xiàn)新突破。

中國地質(zhì)大學(xué)(武漢)的武瑞博士是科研團隊核心成員之一。他表示,為深入了解這6枚珍貴的恐龍蛋化石,科研團隊運用電子顯微鏡掃描等多種技術(shù)手段,詳細進行微觀結(jié)構(gòu)分析。結(jié)果顯示,這些恐龍蛋化石具備獨有的特征組合,如蛋殼內(nèi)有乳突層即白色“蛋青”,且乳突層和連續(xù)層之間(指蛋殼、蛋膜之間)邊界模糊;連續(xù)層中存在大量直徑約為1至2微米的囊泡;等等。這些特征顯示,這6枚恐龍蛋化石均為恐龍胚胎發(fā)育中的受精蛋,其中一枚還殘留一根胚胎骨頭。

近年來,贛州盆地作為世界恐龍蛋化石最為豐富的地區(qū)之一,出土了大量形態(tài)多樣的恐龍蛋化石?!摆M州迷你蛋”化石的發(fā)現(xiàn),為全球古生物研究學(xué)者打開了一扇探索遠古生物世界的窗戶,有助于更加清晰了解恐龍的演化歷程和地球的歷史變遷。
