江西新聞客戶端訊(江西日報(bào)全媒體記者童夢寧)10月16日,記者在贛州采訪中獲悉,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(shí)近3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(gè)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(Minioolithus ganzhouensis)”,系當(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(duì)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(huì)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(yuǎn)古時(shí)期江西境內(nèi)出現(xiàn)過一種未知的小型獸腳類全新恐龍,進(jìn)一步增加了古生物研究領(lǐng)域?qū)M州盆地白堊紀(jì)晚期恐龍多樣性的了解,對(duì)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(shí)在國家自然科學(xué)基金委員會(huì)的大力支持下,由江西省地質(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(dòng)物與古人類研究所、江西省地質(zhì)博物館成立科研團(tuán)隊(duì),進(jìn)行科研聯(lián)合攻關(guān),最終實(shí)現(xiàn)新突破。

中國地質(zhì)大學(xué)(武漢)的武瑞博士系科研團(tuán)隊(duì)核心成員之一。他表示,為深入了解這6枚珍貴的蛋化石,科研團(tuán)隊(duì)運(yùn)用電子顯微鏡掃描等多種技術(shù)手段,詳細(xì)進(jìn)行微觀結(jié)構(gòu)分析,結(jié)果顯示這些蛋化石具備獨(dú)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(指蛋殼、蛋膜之間)之間邊界模糊;連續(xù)層中存在大量直徑約為1至2微米的囊泡等特征。這些特征顯示,這6枚蛋化石均為恐龍胚胎發(fā)育中的受精蛋,其中一個(gè)蛋還殘留一根胚胎骨頭。

近幾年來,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,其中不乏與成體關(guān)聯(lián)的恐龍蛋窩以及含恐龍胚胎的恐龍蛋化石“英貝貝 Ying Baby”。當(dāng)前發(fā)現(xiàn)的“贛州迷你蛋”化石,為全球古生物研究學(xué)者又添了一扇打開窺探遠(yuǎn)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。
