Drunk on Paleontology - Finca El Origen Reserva Malbec

The next Drunk on Paleontology is for Finca El Origen Reserva Malbec from Finca El Origin  out of Mendoza, Argentina.

Clearly this is a wonderful example of Drunk on Paleontology, with the large ammonite fossil spread across the bottle. But before we even get into the fossil, lets take a look at the geology itself. The back of the bottle has a geological description of the wine local:

Text from the bottle:

First is was an ocean. Then mountains and later a mountain range. Now it is home to the high-altitude vineyards that produce wines with a mountain-inspired personality and a complexity and character only this terroir can bestow.

Their website has a little more information on the source of their logo, or at least the inspiration for their logo:

Not only is our vineyard ideal for precision viticulture, but it also the witness of history: A Nautilus fossil was found while preparing the land for winegrowing. These sea snails from the Jurassic period are silent bystanders of the formation of the Andes, which were once an ocean.

Location map from Finca El Origen's website

The winery is located in Los Chacayes, which is in the Valle de Uco, Mendoza, Argentina. It sits right at the eastern base of the Andes Mountains, just over the border from Santiago, Chile. The Andes Mountains, though, are a jumbled up mess of geology, and I can't find very many definitive sources for geological units. I have found two websites that seem to offer some information. 

Geological map of the Mendoza region around Los Chacayes from the Geological Map of South America. Los Chacayes is highlighted with the star. 

The above map is from the "Geological Map of South America", and while a useful source for a general map of the entire continent, it doesn't have very many details for the specific unit we are looking at. Unit "203" on the map, the unit that encompasses the entirety of Los Chacayes, is identified on the map as being from Permian to Triassic in age and comprised of rhyolitic volcanic rocks. And that's about it. Even going to the original document doesn't provide much more information. 

The other map I tried was the "Mapa Geológico Bicontinental de la República Argentina"

This second map also has the same shape of the unit that we are interested in, identified as PTSs. But they have a little more information on the unit. Here it is identified as "Siliciclastic and volcanic rocks, Permian to Triassic in age". And that's about it. Obviously this location would once have been an ocean basin, due to the ammonite fossil found within, but other than that it looks like we are limited at the moment. Looking at the fossil itself: 

The ammonite fossil on the bottle is clearly an artistic rendering of a the ammonite fossil, and I think it is not actually the fossil that was found on the vineyard locality. This is because it seems to match a drawing of an ammonite fossil done over 100 years ago. 

Plate 44 Ammonites in Haekel's 1899 Kunstformen der Natur.

The illustration on the wine bottle seems to match ammonite on the center right in the image above, if we flip the image and adjust for the curvature of the bottle. The lines on the ridges match location placement and numbers, as well as the knobs on the inner part of the swirl.

Comparison of the Finca El Origen ammonite and Haekel's 1899 illustration

The degree of similarity is too much to ignore. Haekel's ammonite illustration is of the ammonite Douvilleiceras mammillatum. While Douvilleiceras mammillatum can be found in many places across the globe, there have been no instances of discovery within Argentina. The closest location to this, is one instance within Brazil, and regardless, Douvilleiceras mammillatum is a lower to middle Cretaceous age fossil (Aptian - Albian), meaning that the rocks within the vineyard are much too old to house this fossil (they are Permian to Triassic in age, at least 80 million years older than Douvilleiceras mammillatum). Therefore the fossil on the bottle is clearly not the one that was found. 

Well then, what was the fossil found?

On the winery's website, they have two pictures of real fossil ammonites among the description of why there's an ammonite on the bottle. The first ammonite pictured is a clear image of a split and polished ammonite (pictured above). Despite being a paleontologist myself, I am far from an expert on ammonites. From my knowledge of ammonites it is exceedingly difficult to identify them with any accuracy based on the internal structure. However, comparing this to other ammonites, this example appears to be an ammonite from much later in the time period, like the illustration on the bottle. From what I can tell, this looks like a cut and polished ammonite from the Albian (middle Cretaceous) of Madagascar. It seems to resemble a Cleoniceras ammonite, like the one pictured below. But in general, this ammonite pictured is again, impossible to have occurred within the time period and region of the rocks within the winery. I have reached out to an ammonite specialist and if I hear anything back I will update.

The final ammonite pictured on the winery's website, is shown below. While this is clearly a staged photo, we will assume that this is a real fossil and that it has the potential to have been found within the region.

Searching for ammonites within Argentina, had found several examples of Jurassic or Cretaceous ammonites that occurred within the Mendoza region, however I did find a few examples of Triassic age ammonites.  

Ammonite pieces from Riccardi et al., 2004.

The above images are of fragments of the ammonite Choristoceras found within the Mendoza region of Argentina in Riccardi et al., 2004. Within the article they state that "Ammonoids in the Triassic part of the section are quite rare and so far only part of a whorl and several external moulds have been found." But with the skewed winery ammonite photograph as our example, this appears to be a match, or at least as close of a match as I can be sure of. Choristoceras is also a Triassic age ammonite that went extinct at the end of the Triassic, making it seem like a likely contender. 

Choristoceras illustration from Steinmann, 1890. 

And some images of complete Choristoceras fossils (pictured above) do tend to resemble the image used on the bottle (although the image used is clearly a recreation of Haekel's image). 

Stylized ammonite fossil on the top of the bottle. 

But regardless, the design on the top of the wine bottle of a stylized ammonite fossil is pretty freaking cool.
