Sepia vindobonensis is a tertiary octopus .

The species lived in the Paratethys Sea, which stretched from the Pannonian region to the Black Sea region about 30–15 million years ago after the intense alpine phase of the young Alps and Dinarides separated this marginal sea from the Mediterranean.

The Paratethys in the Karpatium / Badenium

So far, only a few specimens have been described on the basis of fossilized Schulpe (these are rare because these body parts are very poorly preserved overall):

  • a broken Schulp, find in Baden , Lower Austria (locus typicus); Collection of the Federal Geological Institute ; Determination by Schlönbach in 1869
  • a find in reason ; near Wullersdorf, Lower Austria; Schaffer 1958; Storage unknown
  • two Schulpe 139 × 43.3 mm, 98.3 × 29.9 mm in Devínska Nová Ves , Slovakia Činčurová 1990
  • two Schulpe, 119 × 39 mm (adult), 86 × 29 mm (juvenile) in Retznei, Styria ( Lafarge Perlmoser quarry ); GW Anzenböck Collection (Bad Vöslau); Determination of Hiden 1994/95

Schlönbach determined the species because of the growth lines of the septa (hyperbolic lines running from the sides in the middle), which, in contrast to Sepia officinalis (today's common squid), are not kinked. A team led by Vasja Mikuž gives an assignment to the species via the length-to-width ratio of around 3 as a distinction to other species.

So far , Sepia vindobonensis can only be detected with certainty for the Badenian , the local time stage of the central Paratethys from about 16 to 13 million years ago, which corresponds to the Langhian and lower Serravallian of the Middle Miocene . Biostratigraphically , Sepia vindobonensis can more specifically be assigned to the Lageniden zone , a subunit of the lower (early) Badenium.

Another find, recovered by Roger in 1947 in the Middle Miocene from Saubrigues (south-westernmost France) and identified as Sepia cf. vindobonensis , is too poorly preserved to be compared.
