Paleography - Science topic

I'm interesting in know the periods during the Miocene where the Balearic Islands could have been submerged and, the periods (before the Messinian) where the islands could have been connected to the Iberian Peninsula.

I am reconstructing the palaeography of Tunisia during the Turonian and the Coniacian ages and I realized that some areas are already resistant since the Aptian, Albian and Cenomanian. I wondered if in the absence of a triassic rise, can the deposition of thick volcanic series create a resistance of the sedimentary floor?

Apart from differential preservation and discoloration

I am looking for a protocol to isolate and mount fossil pollen plates from coastal sediments. I have a little experience working with fresh plant material for pollen analysis.

Thanks!

We study an outcrop formed by Middle Miocene sands and clays, which are expected to be deformed during Quaternary. Thanks a lot for suggestions.

This tooth came from a Kimmeridgian locality in Northern Germany, yielding marine sediments. There is also a macroscopic and microscopic content of terrestrial taxa from this locality.

We are confused about the two-cusped shape and the very distincted facet of attritive wear.

Could it be a fish tooth? Similar mammal teeth are unknown until now.
