"...previously unreported..." "...many of them..." There is at least a bit of spin in those words that aren't quantified by your impression of them. What is meant by 'many' in this regard? 12 of them (out of 56) were unreported? Unreported in English-language works, really? Qualify that statement, show me where you or the authors actually combed through all the works of the English language to arrive at such a statement. Show me one example among the 56 for which I cannot find a prior report on in English language works. Some things are written in such a way as to provide editorial impact. But they're not an accurate representation of the historical record by any means.
