US, WASHINGTON (NEWS OBSERVATORY) — This statement was made by specialists from the Free University of Brussels after they had finished researching the shell belonging to the ancient mollusk.
Fossils were attributed to the Cretaceous period and belong to one of the species of ancient mollusks, which was called Torreites sanchezi.
Torreites sanchezi became extinct about 66 million years ago and do not have a single direct descendant to date. But still there are some common features with modern mollusks.
The sink grows in a special way – one layer is added every day. Due to this, you can determine how much the mollusk lived and how many days were in the year about 70 million years ago.
Niels de Winter, along with colleagues was surprised by the result.
They conducted many studies and determined that this mollusk most likely lived in water. After the mollusk shell rings were examined, it was established that he lived for nine years. For each year, 372 rings appeared instead of 365.
This suggests that the day at that time was half an hour shorter.
This phenomenon can be explained by the fact that the Earth begins to rotate more slowly under the influence of the gravity of the Moon, which provokes regular tides on our planet.
