Local floods could not have deposited them without breaking them to bits.
So you agree that Leonardo was wrong about that.
Da Vinci didn't say any fossils were deposited by local floods. He was arguing
against the idea that they could have been deposited by a flood; since many of them clearly grew in situ. He was of the opinion that the whole earth was once covered by sea, but not in any short term flood. The fact that fossilised corals which show no sign of having been uprooted and deposited by any flood are found in the Alps, showed him that the Alps must have been under the sea for many years.
The full book of his collected notes is available on Sacred Texts
here, by the way. His thoughts on the flood and fossils are collected in Chapter 16 in the second volume.
