اكتشاف بقايا دم في عظام ديناصور عمره 115 مليون سنة

ما يعرفه ريفو عن الخبر

عثر فريق بحثي دولي على خلايا دم حمراء متحجرة وجزيئات هيموغلوبين داخل عظام ديناصور عاش قبل 115 مليون سنة في البرازيل.
أثبتت التحليلات وجود جزيئات كيميائية مشتقة من الهيموغلوبين وأحماض أمينية من بروتين الكولاجين داخل القنوات الوعائية للعظام.
ساهم معدن الهوسمانيت في تثبيت التراكيب الخلوية وحمايتها من التحلل عبر ملايين السنين.
يفتح هذا الاكتشاف آفاقا جديدة لدراسة الخصائص الفسيولوجية للحيوانات المنقرضة وتطور عمليات الأيض.
