The most famous fossil in Val Gardena is definitely the ichthyosaur found on the Seceda mountain. This large marine reptile, around 5 meters long, was the largest predator of its time (241-240 million years ago). As much of its skeleton is missing, it cannot definitely be allocated to a specific genus. Yet it remains a very significant discovery, as it is practically unique in the Early Ladinian period, a time of crisis for these marine reptiles.

Ammonites were cephalopods, relatives of today's nautilus, octopus and squid. They are extinct now, but used to be among the most common organisms living in the Triassic seas. There are many examples of their fossilised remains, ranging from perfectly 3-dimensional to completely flattened. The rapid morphological changes in many groups make them an important tool in rock dating. Many species in fact only lived for a few thousand years.

Along with few other molluscs, the bivalve genus Claraia is among the organisms that best adapted to the critical environmental conditions of the coastal sea waters after the extinction event taking place 252 million years ago. Remains of other organisms are only occasionally found in association with Claraia, showing just how extreme the environment was. It was apparently the only one surviving under these conditions.

This fossil fish is unique. Thanks to the microfossils contained in the rock, it could be dated back to the Permian-Triassic extinction event (about 252 million years ago). This was a crucial moment in the Earth's history, when life itself was threatened with extinction. Archaeolepidotus represents the Parasemionotiformes, which were already around in the Late Permian and then underwent extensive development in the Early Triassic. The majority of today's fish originate from this group.

A footprint in the wet sand that time has turned into today's Val Gardena Sandstone is all that is left of the Pareiasauroidea, a large and stocky primitive reptile that grazed off foliage near rivers and streams. This creature can be regarded as a type of Permian 'cow', even though grass didn't exist at the time - only ferns and other plants, such as the Ortiseia conifer.
