Jack Kallmeyer replied to the topic Microscopes for Cleaning and Photographing Fossils in the forum Fossil Prep Tips & Tricks Forum 4 years, 10 months ago
4 years, 10 months ago4 years, 10 months agoI can only address cleaning as I don’t use a microscope for photography (macro lenses only).
A stereoscope with step-wise or variable power is the best for cleaning small specimens. Larger specimens can be worked on using a ring light with a magnifying lens in the center. The key is you want both of your hands free to manipulate and work on t…[Read more]

Florida’s Fossils 4 years, 11 months ago4 years, 11 months ago4 years, 11 months agoAnyone on here ever see this video? https://www.youtube.com/watch?v=T_HqYfzIHVo&feature=youtu.be The fellow is collecting fossil shells in Florida at night using UV flashlights. He finds a lot of cone shells with color preservation that only shows with the UV light. Anyone know the age of these fossils or where he might be collecting?

I can’t open the link, but I believe it’s the video by PaleoCris? I saw it too, absolutely crazy. I believe Cris mostly hunts in the Nashua Formation (Pliocene) when it comes to shells, but I’m not too sure if this location is also from that formation.
-
Max, yes it is paleochris. I don’t know why the link didn’t work so here’s another: https://www.youtube.com/watch?v=T_HqYfzIHVo . So whereabouts in Florida is the Nashua Formation?

Thanks for sharing this video Jack!

Sure! This is the first time I have seen color patterns show up with UV but these are fairly recent fossils – Pliocene I believe. I have gone somewhat nuts on fluorescent minerals and stumbled on this on one of the sites I check for that phenomena. Many of our fossils have some degree of fluorescence – usually the calcite which gives an orange…[Read more]

Cincinnatian Collectors 5 years, 1 month ago5 years, 1 month ago5 years, 1 month agoHere’s another set of pelecypods to check into. Caritodens demissa is one of the few that have shell preservation rather than being internal molds. This group shows “babies” under 5mm across the shells.

Cincinnatian Collectors 5 years, 1 month ago5 years, 1 month ago5 years, 1 month agoI usually only keep pelecypod fossils that are well preserved. Here in the Cincinnatian most have no shell preservation and are only internal molds. These molds are subject to deterioration and poor preservation such that some no longer look like pelecypods at all. This attached is an exceptional specimen about 50 mm long. This is an int…[Read more]

That is an excellent find and extraordinarily preserved! I have a few nicely preserved specimens from near Flemingsburg – where is yours from?
-
This specimen comes from Causeway Road across Brookville Lake. Mollusc preservation is pretty good at the lower end of the exposure – Waynesville Fm.
-
That’s spectacular. I don’t think I’ve ever collected there!
-
I hated this site when I first collected it – found nothing. On my next visit I started finding crinoids so I spent many trips there. I ended up collecting 9 different crinoid species from the Liberty part of this exposure plus one partial ophiuroid. I have suites of crinoids from here with at least two such suites waiting for data collection…[Read more]

Jack, on your Causeway Road bivalve without an ID (very nice specimen BTW), I would suggest it’s Rhytimya sp. There is a similar specimen from the Fairmount pictured in “Review of Ordovician Pelecypods”, Pojeta, Plate 16, figure 10. That one is R. mickelboroughi (Whitfield). But your Waynesville or Liberty specimen is probably R. faberi (Miller),…[Read more]

Bill,
I looked at the Ohio Geological Survey VII and there are quite a few Rhytimya sp. I think you are correct with your ID. Thanks. Dalve 1948 is not illustrated. What publication and year is the Pope reference?

Eclectic Echinodermata 5 years, 1 month ago5 years, 1 month ago5 years, 1 month agoHere’s a crinoid collected by a Dry Dredger years ago. It is now in my collection. It is Eucalyptocrinites elrodi from the Silurian Waldron Shale of Indiana. This is one of the less common species in this Formation. It is exceptional because the arms are preserved in place. Usually the arms and the upper part of the cup are missing. Scale bar…[Read more]

An excellent fossil! I was working in the Yale Peabody Collections several years ago and was rummaging around looking for hidden blastoids (as one does) and found a Eucalyptocrinites identified as a blastoid! I can see the confusion, the arms being folded up so neatly look similar to the blastoid ambulacra. The way these preserve is really spectacular.

I have not looked into Great Courses but I have participated in a course on edx.org – it was in physics though. It looks like they don’t have a great selection for Earth History or Paleontology.

Florida’s Fossils 5 years, 2 months ago5 years, 2 months ago5 years, 2 months ago@tim-collins Great find! My collecting at Venice with a Florida snow shovel yielded interesting material but no Meg teeth
-
I found mine back around 2000, so maybe the area’s been picked over? It was sticking out of a small shelf of sand that ran along the water where the waves had eaten away at the beach.
-
My stuff came from a family vacation years ago. They’re actually from Casperson (?) beach just south from Venice Beach proper. I unfortunately left my car unlocked in the excitement of getting to the beach and we got robbed. Ahhh, good times.

Bookworms 5 years, 2 months ago5 years, 2 months ago5 years, 2 months agoAnyone else interested in paleoanthropology? I am quite fond of Neanderthals myself. Here are a few books from my library on that subject.
-
Very cool! I know @molly-selba works in human evolution. The Smithsonian used to have an app that would morph your face into a few different Neanderthal species – I remember really having a good time with it!!
-
I used to work with a guy who wouldn’t need much morphing. He had heavy brow ridges and huge canine teeth. By the way, those are only two of my Bone Clones Neanderthal skulls. That is all I could fit into my display.
-
Wow! Bone Clones! That is really awesome! I keep thinking I’ll get a 3D printer one day and print all the skulls I could possibly want! Colin and I printed Homo naledi – took 20 hours!
-
Bone Clones has a complete Neanderthal skeleton too! If I had unlimited funds I’d have one for myself.

@molly-selba That is really nice! How did you get the digitization of the skull in order to make the 3-D print? Is this a generic skull or a specific one? The two I showed in my photo were: La Ferrassie I (R) and Teshik Tash (L). I also have La Chapelle-aux-Saints I

Great recommendation, @jkallmeyer! I definitely need to work on my shark tooth identification. My current identification process: ‘does it look shark-y’ and ‘is it pointy’.

Florida’s Fossils 5 years, 2 months ago5 years, 2 months ago5 years, 2 months agoLori, your specimen appears to be a coral as near as I can tell. It will be preserved as calcite. Consequently, so not use anything acid or acidic on it as it will dissolve the fossil or at least damage the surface. If it doesn’t clean up with a toothbrush, soap and water you could try an ultrasonic cleaner with detergent.

I appreciate your time, Jack. Thank you
