There is no evidence that da Vinci consulted [[Arabic]] texts on this issue. To say that he added nothing original to the Arabic findings is highly uncharitable.  

At about 540 BC, Xenophanes described fossil fish and shells found in deposits on mountains. Similar fossils were noted by Herodotus (about 490 BC) and by Aristotle (384 - 322 BC). Aristotle believed volcanic eruptions and earthquakes were caused by violent winds escaping from the interior of the earth, thus perhaps making the first breakthrough in the human understanding of geology.
