Fossilised red blood cells found in 115-million-year-old dinosaur bone

11 کروڑ 50 لاکھ سال پرانی ڈائنوسار کی ہڈی میں سرخ خون کے خلیے ملے

115 मिलियन वर्ष पुरानी डायनासोर की हड्डी में लाल रक्त कोशिकाएं मिलीं

Fossilised red blood cells found in 115-million-year-old dinosaur bone

Key points

اہم نکات

मुख्य बातें

  • Scientists say they have found the strongest evidence yet of red blood cells in a dinosaur fossil, in bone from a medium-sized meat-eater, Aratasaurus museunacionali, that lived in what is now Brazil about 115 million years ago.
  • Researchers found microscopic structures that look like fossilised red blood cells in the leg bone, plus chemical traces of heme, the iron-containing molecule linked to haemoglobin.
  • The study, published in Proceedings of the National Academy of Sciences, does not show dinosaur DNA, the researchers stressed, but a mineral and molecular echo of ancient biology.
  • سائنسدانوں کا کہنا ہے کہ انہیں تقریباً 11 کروڑ 50 لاکھ سال پرانی ڈائنوسار کی ہڈی میں سرخ خون کے خلیے ملے ہیں۔ اس طرح کے نرم ٹشو عام طور پر فوسل بننے کے عمل میں محفوظ نہیں رہتے، اس لیے یہ دریافت غیر معمولی طور پر نایاب ہے۔ محفوظ شدہ خلیے محققین کو ڈائنوسار کی حیاتیات اور ان کے جسم کے اتنے عرصہ پہلے کام کرنے کے طریقے کے بارے میں مزید جاننے میں مدد کر سکتے ہیں۔
  • वैज्ञानिकों का कहना है कि उन्हें लगभग 115 मिलियन वर्ष पुरानी डायनासोर की हड्डी में लाल रक्त कोशिकाएं मिली हैं। ऐसे नरम ऊतक आमतौर पर जीवाश्म बनने की प्रक्रिया में सुरक्षित नहीं रहते, इसलिए यह खोज असाधारण रूप से दुर्लभ है। संरक्षित कोशिकाएं शोधकर्ताओं को डायनासोर की जीवविज्ञान और उनके शरीर के इतने लंबे समय पहले काम करने के तरीके के बारे में और जानने में मदद कर सकती हैं।
