Reading-研究者一直苦于发现不了bone tissues.但是最近对某种恐龙bone leg 的研究为科学家们提供了一些tissue存在的证据。

1. Channels(regarded as blood vessels)
2. Red blood cells
3.Collagen remains

Lecturer认为阅读中的证据Skeptical。
(1) The material found in the breaking of the bone can not prove the existence of red blood vessel. It is more likely to be other material such as the reddish mineral.
(2) Sphere also appears in other animals that do not have bone tissues. For example, it may be the traces left by the bacteria colony that lived in the bone leg after the dinosaur died.
(3) Collagen can not remain as long as a period of 70 million years. So it is more that the collagen comes from other recent sources such as the human skin of some researcher who handled this bone leg before.
