Thanks Steven!

 

 

 

Here are my two latest acquisitions. That's a female Keichousaurus on the left, and a subadult male on the right. I don't usually get Keich, but these two were too pretty to pass up.

[Macrophyseter]

Really nice keichos there andy!

[aplomado]

Awesome!  How do you sex the Keichousaruses?

I don't often get trilobites or plants, but these two were too pretty to pass up.

I am lacking info for this guy here. The seller's description is:

 

CARBONIFEROUS FERN
Callipteridium gigas, Pecopteris, etc. .
Estephanien B. Cantabrian Mountains. Spain.

To tell the difference, look at the humerus, ulna & radius. In male, they are longer and broader. The following pics show the difference:

Here is additional info to update your label:

Drotops armatus is early Givetian ~387 Mya and recorded from the Bou Dîb Fm at Zireg or the Taboumakhloûf Fm at Jbel Issoumour.

 

 

According to McKellar & Chatterton 2009, it is probably from the Bou Dîb Fm:

 

"Alternative specimens (figured here) were commercially mined and likely come from the equivalent Drotops armatus couche outcropping at Zireg (farther southeast). Strata are Givetian in age, and part of the Bou Dîb Formation (Campbell et aI., 2002; Bultynck and Walliser, 2000)."

Augustidens with an amazing shine

A set of dinosaur eggshells

Thank you!

 

Hi,

 

for your eggshells from France, the 3 types are Megaloolithus sp (probably mammilare) the one in the left corner is just eroded. They are eggs from either Rhabdodon or Titanosaurus.

Cairanoolithus is totally smooth (and a recent study tends says it would come from Nodosaurus).

 

[Tidgy's Dad]

What an incredible collection! 

Please keep posting these fossils are simply astonishing.

I still say that's a Halisaurus walkeri. All the H. arambourgi jaws I've seen do not have teeth that far back on the dentary, while H. walkeri does. But regardless, it's a nice jaw.

Thank you. The current names was the info I got off the sellers. When you said left corner, you mean the Hypselosaurus?

 

Are all eggshells from France of the Megaloolithus type? I just got another titanosaur-type from Meze, France.

Thank you. George Corneille mentioned this species too. I shall do more research into this.

Glad you like them!

[Troodon]

Nice adds, I especially like your two bugs and understand why you could not pass them up.  Your cabinets look like they are full, guess you will not be able to add much more 

[ynot]

You have too much good stuff!

Indeed Hypselosaurus (by the way, it is a name which has been deleted now because not valid) should be replaced by Megaloolithus sp (same as upright corner).

See this link, last page figure (a): the same weathered surface as yours.

For the 2nd one in the lower rank it is also Megaloolithus sp from Rousset.

 

That's quite difficult to navigate in the oo-types of eggs, sometimes the difference is difficult to find... today I think the main species from South of France are:

- Megaloolithus mammilare (the most common) / microtuberculata /  aureliensis / siruguei / petralta

- Cairanoolithus roussetensis / dughii

- Prismaloolithus caboti / matellensis / tenuis

 

Hope it helps

Missed this, nice new adds.  Like the Vert string very much and the Basilosaurid is awesome

Love the Basilosaurus tooth

Thanks for the kind comments, everyone!

Thank you! It's not a Basilosaurus tooth. That's the common marketing name used by sellers. There's no way to know if these kinda teeth belong to the famous Basilosaurus we remember from TV. There were many prehistoric predatory whale with similar teeth. I call it Basilosaur as it more broadly describes the family as a whole. More accurately, you could call it 'Archaeocete indet sp.'

Excellent acquisitions! Plesiosaur and Archaeocete material is some of my favorite marine predator material to collect. Plesiosaurs had such beautiful vertebrae. That associated chain is a top notch specimen!

Such an impressive collection Andy! Thanks for posting these excellent and informative photos.
