color patterns

[rocket]

Today I did some pics of a huge piece of rock from the famous (today closed, forbidden to dig...) basalt-pit Weitendorf near Graz in Austria. It was miocene vulcanism covering sweetwater-sediments containing lot of snails, shells, rarely crabs and other fossils.

Some of the snails are preserved with color patterns, but it is rare.

So, when I did the pics and worked on them last hour I found two of them. One is Natica tigrina millepunctata, I think this gots the name "millepunctata" due to the lots of dots 

Size is approx. 2 cm, small one, but perfect!

Yeah, that´s really not common having the pattern on a Natica. Great!

 

Its quite common to have a pattern on Conus snails at this site:

 

A few km away, you need an UV light:

 

You are not allowed to enter the quarry freely, but the fossil bed is now (at least it was from 2016-2020) exposed in an area (Tiefbau) that is not within by the rather small natural monument (Which is mostly covered by debris).

 

This hole, however, was dug into the natural monument:

wow, very nice, thanks for showing! Always a "wonder" that patterns and color could be preserved over millions of years..., I think I do not look so pretty in the year 15 000 000 b.c. 

 

Some years ago there was a nice report about the site and color pattern In the german Fossilforum STEINKERN, Steinkern.de - Die Fossilien-Community - Die Weitendorf-Sammlung von Herbert Schlemmer

You sure know that Vitta picta and other stuff ?
