[Rockhounds] Florida silicified shell fossils

[EDWARD J WAGNER]

Hello, guys:
I was on the web  this morning, to try to suggest UV on these items. they glow white, cream, or bright yellow, depending where the shells are, the position and concentration of the calcite xtls, and the prices have been relatively high, due to the restrictions on collecting at Druck's Pit, (the original hole is below water at 35ft., and the current Drucks collecting area has been relegated to the adjacent property.    I have about 12 shells, 3 chunks of coquina, the concentrated upper leven limestone material, and several calcite on/in shells. Most fluoresce well, and there is a slight change of intensity from LW to SW, but not by much. These are really beautiful, but florida has a lot of coquina, and most of the area was seabe,

 Some decades ago, on a Friday in
 1985, I thought it was strictly amateur too... Oh boy,
 that's how it starts 😉

 Those look
 similar to the ones from the tourist spot over in Fort
 Drum.  My
 father-in-law collected some
 while traveling there.   I havent been lucky
 enough myself to be down in FL in some 30 years
 when i was a teenager.
 
 Anyways, the calcite glow nice on mine (ex
 pap's) under UV!

 Howdy folks.  A
 year or two ago, there was some chat here about silicified
 Florida (USA) shell fossils -- not to be confused with
 well-known Tampa Bay area agatized coral.  I mentioned that
 I'd collected a handful in North Miami Beach back in the
 1970s.  Here's a recent photo of them:

 Also I talked with someone
 off-list about these rocks, but then I couldn't find the
 originals in my growing collection!  Well recently while
 doing sorting and high-grading, I found the flat, and this
 is what they look like (photo URL above), with a penny for
 scale.  Note that some broken pieces show yellowish quartz
 crystals inside.
 
 The
 two-sided bivalve cast on the right end of the third row is
 the coolest...  It's translucent when you hold it up to
 the sun.
 
 I wish I'd
 spent more time back then collecting on this scraped-off
 open field before they built a suburb on top of it!  Just
 from memory, I think the location was around 25.95397
 -80.16272; paste into Google Maps to see where.  While I
 know it was west of some like in the area, not sure I have
 the right one!
 
 Cheers,
 Alan Silverstein
