Abstract The carbonate Transgressive Systems Tracts included within the two Depositional Sequences from the "Muschelkalk" of Pyrenees (DS2.17, Late Anisian - Early Ladinian and DS2.12, Late Ladinian-Carnian pro parte) contain assemblages of alpine-type benthonic Foraminifera and palynomorphs. The first sequence is pointed by the local presence of Meandrospira gr. pusilla-dinarica which was only recognized in the Spanish Pyrenees, not studied herein. The second one includes a diversified microfauna which is relatively constant along the totality of the range, Spanish Pyrenees included. The corresponding assemblage, illustrated for the first time in this part of Pyrenees to the East of the Garonne, is characterized by numerous lnvolutinacea (Aulotortus praegaschei, Triadodiscus eomesozoicus and Lamelliconus multispirus) and also by Endothyridae (Endothyranella wirzi), Duostominidae and Glomospirillinae. This assemblage is similar to the synchronous one which was recently quoted in the Catalonian Pyrenees, Balearic Islands (Minorca) and Corsica.
