This video is called Miocene fossil clam Pseudolarix amabilis, October 4 2019.
On 13 January 2019, again to Naturalis museum.
Once again, to its Life Science hall.
Marian was working on many, mostly very small, fossils from the Tortonian age; part of the Miocene age; over 7 million years old. The fossils were from France.
There are thousands of seashell species represented in the fossils. As it was then warmer, there was more biodiversity.
Marian sorted the fossil shells according to genus. Later, specialists would do research on the species.
Next to Marian, work was in progress on classifying 500,000 unclassified butterflies of the Naturalis collection.
This October 20189 Dutch video is about the Naturalis collection.
