Dinosaurs finding around 1600?

[Fabienne Gallaire <gallaire@clipper.ens.fr>]

Hi!
I'm a student in History of Sciences and
I just subscribe to this mailing list in order to ask your opinion about a
question I encountered studying a text by a alchemist physician and
chemist (Treatise of signatures, by Oswald Croll or Crollius).

Here is the quote:

"As once in Moravia three miles from Brunna not far from the territory of
the Abbot of Abroviensis, under a most high rock, were dug out the bones
of two unknown animals of unusual magnitude, together with two of the same
likeness younger, which without doubt perished in that solitary place in
the time of the Deluge of Waters; some relics of which bones, and
wonderful teeth I caused to be dug up, and in Medical use found them not
to want much of the efficacity that is attributed to Unicorn Horn."

Sorry for the bad translation from Latin.
Here is my problem: as far as I know, not much dinosaurs were dug up circa
1600, and the first I've found with a post Linnean name and the name of
the finder is Scrotum humanum (Brookes) a mere bone named in 1763.
If you have any information about dinosaurs before 1750, please give me
your references.
My other problem is that I haven't been able to locate Brunna so far
(Slovaquia,probably): this done, I guess I will find out a little more,
because four dinosaurs in one place doesn't happen every day..

Please feel free to submit me any hint or hunch you might come up with!
