Hi fossils friends,
here is a little taphonomic accumulation plate with many Olenekian (lower Triassic) Ammonoids.
It comes from the Vikinghøgda Formation - Sassendalen group (Sassendalen valley - Spitsbergen island - Svalbard archipelago - Norway)
Most of the Ammonoids are Svalbardiceras spitzbergensis (Freblod, 1930). Associated on the plate is an unidentified orthoconic Nautiloid (never seen this in the associated litterature), a bivalve and a partial Ammonoid from the Hedenstroemiidae family (at the top-left).
Size of the plate is 11,5 X 9,5 cm.
I prepared it with my Dremel engraver in about 8 hours.
