Titanothere vertebra

Chadron Formation, Oligocene

I found this on forest service land during geology field camp in 1998. Collecting was allowed as long as all finds were photographed and documented at the time.

 

Fossils from the Chadron are considered Late Eocene.  Titanotheres died out in North America at the end of the Eocene.  I should note that older references did state the age of the Chadron beds as Oligocene and the end of the Chadronian (based on the Chadron beds) does not exactly coincide with the Eocene-Oligocene boundary so I might be corrected at some point regarding the first sentence in this post.

I now barely remember being told during field camp that the Chadron is Eocene. It is uppermost Eocene, so the pattern in this thread isn't quite broken. :)

 

The boundary with the Cretaceous Pierre Shale, on the other hand, was quite dramatic.

I think we might have skipped the Paleocene so here’s a couple of  Scyliorhinus entomodon from the Paleocene of Morocco (Ben Idir specifically)

Pleistocene Tiger Shark Tooth from Galveston Texas

Technically, it's a sand tiger shark (aka sand shark).  Galeocerdo is the tiger shark.  Nice specimen in any case.

Agerina quadrata, Lower Ordovician, Fezouata Formation, Zagora region. Morocco

IMG_20220402_144937703.thumb.jpg.e12dbd13bb49d88ab106e49650984354.jpg

 

Agerina sp. from Morocco has not been formally described yet in the literature. Congrats on this excellent assemblage! 

 

Karim & Adrain 2022:

 

Chatterton and Fortey (2008) have illustrated large clusters of articulated specimens from the Zini Formation (?Floian), Bini Tinzoulin, north of Zagora, Drâa-Tafilalt Region, southern Morocco, which they assigned to a species of Agerina. This taxon has not been formally described.

 

Martin et al. (2016) noted that a species of Agerina was a common component of trilobite faunas of the Fezouata Biota (Fezouata Shale (Floian part only), Zagora area, Drâa-Tafilalt Region, southern Morocco). They named one of their three newly identified biofacies the “Agerina biofacies” and identified the species as Agerina quadrata (Dean, 1966). This is in keeping with their assignment of several other Fezouata taxa to species described from the Montagne Noire, but as yet much of the Moroccan fauna, including the Agerina species, has not been described, so the assignment cannot be evaluated.

I don't have any Pre-Cambrian fossils and that stuff has always been hard to get besides maybe stromatolite slabs so I go to the Cambrian now.  Here's an Olenellus positive and negative from the Early Cambrian from a site around Pioche, Nevada.  It appears to be about 15mm long (unclear where it ends)  It's the oldest fossil I have other than some other Olenellus specimens.  This might be the best one.

A specimen of Mucrospirifer thedfordensis from the Middle Devonian Traverse Formation of Silica, Lucas County, Ohio.  It's about 40mm wide and is one of my "old" fossils.  It was bought at a local show not long after I started collecting them.

 

I always liked Mucrospirifer because it looks like a spaceship - something out of "Buckaroo Banzai."  Some of the ones I've seen are wider and taper out rather thin at their extremities.

Here's what appears to be a rather large Orodus, a Paleozoic shark.  This form might have a different name now but that's what we called it in the 90's.  It's Mississippian age (Early Carbonifereous), Osagean, Upper Burlington Formation, Biggsville, Henderson County, Illinois.  It's about 31 mm wide.

 

I bought this at the MAPS EXPO in 1994 or 1995.  One of the sellers had come across a large temporary exposure of the Upper Burlington and there were numerous broken up chunks with teeth showing on many of them.  He brought a load of it to the show and sold them rather cheaply.  I was unaware of the feeding frenzy but Fossilselachian was kind enough to come over and notify me.  I was able to get a few great specimens even after my fellow shark tooth collectors had picked out some stuff.

 

This thread gives me an excuse to shoot the other pieces I have.
