When Earth experienced lesser daytime during Dinosaurs reign

While the study of dinosaurs is exciting about how they lived, what they used to eat and much more a new study says that Earth didn’t experience 24 hrs in their time, the exact time then was 23 hrs and half-hour. 70 million years ago.

According to Niels de Winter, “We have about four to five data points per day, and this is something that you rarely get in geological history. We can look at a day 70 million years ago. It’s pretty amazing.”

That old timekeeper is a wiped out rudist shellfish, one of a gathering of mollusks that once commanded the job that corals fill today in building reefs. The shellfish had a place with the animal types Torreites sanchezi and lived 70 million years prior in a shallow tropical seabed, which is currently dry land in the mountains of Oman in the Middle East

This old mollusk became incredibly quick from its home in a thick reef, making a development ring on its shell for each day of the nine years that it lived. A gathering of specialists examined the mollusc’s shell to get a depiction of what time and life resembled in the Late Cretaceous time frame, around 5 million years before the narrative of both the dinosaurs and these shellfishes finished.

De winter also stated that “Rudists like Torreites sanchezi mollusks are quite special bivalves. There’s nothing like it living today. In the late Cretaceous especially, worldwide, most of the reef builders are these bivalves. So they took on the ecosystem building role that the corals have nowadays”

With this ancient shell, the scientist is able to detect the seasonal changes, how the weather behaved and so much more in this region. It is also known that high temperatures used to happen in that era, in Summer it used to exceed till 40 degrees while Winter used to experience 30 degrees.

Determining the growth rings have allowed the scientists to basically study the precise value of daytime at that era. Also, Earth used to cover its time by rotating 372 times instead of 365.
