It seems that this thread may be winding down. Maybe a half dozen of us posting .    I had hoped that many members would take this opportunity to show their finds

 

Well, I think many are just busier during this holiday season.  This thread might get more action as January gets going. 

 

I still have a few photos to post but have been unable to time it right for the Devonian, Jurassic, and Cretaceous.  I might be able to get some other stuff shot next week.

I think she meant, it shows the monument from an angle we never get to see in photos.   We usually only see the frontal view.

Thanks @hemipristis

 

You are right Eric. In french "face" means the face (or facial, head), but also the faces of a die, or an angle of view. It is not always easy when English is not our original language. Thank you for explaining it beetter than I done

That was my intent. Showing an unfamiliar angle adds some extra sense of place

I'm enjoying your Precambrian geology shots. I have a big chunk of the rose quartz from there (not that I collected myself, it came to me thru the usual rockhound network).

Is that it in the lower part of the first photo? I've never seen shots of it in situ.

 

Yes it is. The stuff had been thoroughly worked over the years

Granitic pegmatite

Proterozoic

Near Mount Rushmore, Black Hills, South Dakota, USA

 

 

Large feldspar crystal in granite:

 

 

Rose quartz:

 

 

Can't leave out Mt. Rushmore itself:

 

 

 

It's been 30 years since I visited Mt. Rushmore - visited Black Hills Institute on the same trip.  As I recall, you approach the monument from around the side.  The road curves around it rather than the approach being straight at it.

A collection of speartooth shark teeth, Glyphis glyphis, Late Miocene, Sumatra, Indonesia.

 

This is a close cousin to the Ganges River shark, Glyphis gangeticus, which has a nasty habit of eating people in India and Bangladesh.
 

The uppers have a superficial resemblance at a glance to great white uppers, but they are very flat in cross-section (like Carcharhinus plumbeus), with fine to medium serrations, and a Carcharhinus root. They’re not nearly as robust.  The lowers are elongated, with a slight expansion at the end, giving them a slightly phallic shape.

 

One doesn’t see these for sale much, if ever. But being in the region, I got to “know a guy”, lol. These are about maximum size for the species.

 

 

I think they are similar to C. plumbeus teeth as well - the more compressed flatter crown of them.  These Glyphis teeth were harder to find on the market in the 90's.  I started seeing them more often maybe 10-12 years ago.  I don't remember seeing the lowers back in the 90's.

Stigmaria ficoides (17x13cm.) from a spoil pile in Zbuch, Czech Republic. Found on a break during a business trip to Hungary. Late Carbon, Late Muscovian, Westfal D Formation.

 

[Missourian]

Burrow filled with microfossils

Hickory Creek Shale, Kasimovian/Missourian Stage, Pennsylvanian

Wilson County, Kansas, USA

 

 

Micros include forams, ostracodes and possibly algae:

 

[DarasFossils]

Richard's Spur Quarry, Oklahoma

Permian

Unidentified Reptile claw, likely Captorhinus

I purchased online in a big lot of Richard's Spur Material. There was a lot of variety but I am guessing they are mostly from Captorhinus because of how common that creature is in the area. 

Finally something I can post!

I too, purchased some material from that locale.  I cannot fathom the patience and care to recover such tiny bones. My hat is off to the collector.

 

I suspect we are not alone.  Perhaps a Richard’s Spur thread in the future?

Triassic, hm, nice plate with small starfishes (Aspidura) and shells, Muschelkalk, Alverdissen/NW-Germany

Size of each starfish is approx. 1 cm

 

[Paleorunner]

From the Toarcian Jurassic, this 13.5 cm Hildoceras
Belmont - France.

It was acquired through a winning bid in an online auction, in which the lot included three ammonites from the same quarry, (Hildoceras, Grammoceras, and Porpoceras).

 

I don't understand why some photos come out upside down.

Yesssss! Taking advantage of these dates, and the tablecloth on the living room table....
And I also take this opportunity to wish you all............

Would love to see that! I can't imagine how you'd recover bones that small. This one is significantly smaller than my fingernail. I also have some vertebrates, jaw sections, and limb bones. Maybe we can help each other identify them, I'm not super knowledgable but it'd be nice to have a thread to compare specimens. I posted a thread a while ago and someone said one or two out of mine might be a synapsid or amphibian which would be exciting!

I will be receiving a package of jaws/teeth from this formation soon also and a thread to discuss them would be great!

Christmas-Time, I will post an Angel 

Unidentified Fly, Oligocene, Cereste/France, maximum size approx. 9 mm

 

[Ludwigia]

An Otodus (Carcharocles) angustidens tooth with a slant length of 4.5cm. Found in the South Carolinan Oligocene near Charleston and received on a trade a few years ago.

 

[Ludwigia]

Oops! Looks like Frank beat me to it by a couple of seconds.

[fossilsonwheels]

Undescribed Otariid 

Miocene

Round Mountain Silt

Kern Co California 

 

This unusual STH tooth is most likely from a very early Fur Seal according to Boesse. It’s definitely our most interesting marine mammal fossil. 

[Ludwigia]

Neptunia contraria (8cm. long) from the Pliocene Van Lilo Formation at Antwerp, Belgium. Obtained on a trade with Manticocerasman back in 2015. My, how time flies!
