竊蛋龍與現代鳥類孵育效率之熱傳遞比較
from 三瘋資料庫 · host 一天瘋三次
這項研究透過傳熱實驗與電腦數值模擬，挑戰了竊蛋龍具有類鳥類「體溫接觸孵化」行為的假設。研究團隊重建了河源龍與納美格特母龍的實體模型及蛋窩，發現在寒冷與炎熱環境中，成年恐龍的身體僅能部分接觸外環蛋，導致內外環蛋之間存在顯著溫差，孵化效率低於現代鳥類。實驗結果顯示，這種溫度分布不均會造成非同步孵化現象，且內環蛋通常比上方的外環蛋更早孵化。研究指出，竊蛋龍可能並非完全依賴體溫，而是結合環境熱源進行共同調節，成年個體的主要作用在於穩定巢內溫度並減少極端氣候的影響。這項發現為恐龍生殖生物學與鳥類孵化行為的演化提供了新的科學視角。 -- Hosting provided by SoundOn
