而A也只是客观的说法，unjustified不是指作者的态度，说的是在availabe to De Ricqles 的证据 对与这个caution是unjustified的。显然啦，De Ricqles说这个caution的时候他没有证据，所以只能是caution了。那个bone里面的ring是后来发现的。

我觉得A的evidence available to dP有问题，这个evidence概念太模糊，和文章里提到的几个evdidence并不一定是完全重合的。dP提出这个caution，谁知道他是根据什么得来呢？？文中并没有提到，没准他自己已经找到其他evidence证明出来了，但是没公开呢。。。也许这个说法有点强词夺理，但是A的信息从文章中是推不出来的
虽然又发现了bone ring，但大家也只是怀疑dinosaurs可能有intermidiate structure，但作者特别都强调用了不确定的说法，如This question remains unanswered; indeed, taking all the evidence into account, one cannot make a definitive statement about dinosaur physiology on the basis of dinosaur bone. It may be that dinosaurs had an intermediate pattern of bone structure because their physiology was neither typically reptilian, mammalian, nor avian.

以下是引用BiteGmat在2005-5-3 17:28:00的发言： D项中的“given certain subsequent findings of other scientists”怎么解释呢，好像文中没有提到嘛
意思是“鉴于其他科学家在此后的某些发现”。 Although de Ricqlès urged caution, arguing for an intermediate type of dinosaur physiology, a generation of paleontologists has come to believe that dinosaur bone is mammalianlike. In the 1980’s, however, Bakker’s contention began to be questioned, as a number of scientists found growth rings in the bones of various dinosaurs that are much like those in modern reptiles. Bone growth in reptiles is periodic in nature, producing a series of concentric rings in the bone, not unlike the growth rings of a tree. Recently, Chinsamy investigated the bones of two dinosaurs from the early Jurassic period (208-187 million years ago), and found that these bones also had growth rings; however, they were also partially fibrolamellar in nature. Chinsamy’s work raises a question central to the debate over dinosaur physiology: did dinosaurs form fibro-lamellar bone because of an innately high metabolic rate associated with warm-bloodedness or because of periods of unusually fast growth that occurred under favorable environmental conditions?
