Dinosaurs ruled the Earth 65 million years ago, but they did so when the day was shorter than it is now, according to newly published research.

The study, which was published in Paleoceanography and Paleoclimatology, and looking to an extinct rudist clam, and found out that it was supposed to be a growth ring on the shell) for each day of the nine-year-old that he was alive. The researchers used lasers to find the data points that is approximately 70 million years ago, and one day, about a 30 minutes shorter, and a year, for about 7 days.

“We have about a four-to-five-points-per-day, and this is something that you are almost never in its geological history,” said the study’s lead author, John Winter, an analytical geochemist by the Free University of Brussels, belgium, in a statement. “Well, We could, in principle, on a day that is 70 million in the year-ago period. It’s pretty amazing.”

The experts can take a look at the shell —is made up of two parts, held together by the hinge, and found that the ocean temperatures have reached 104 degrees Fahrenheit in the summer and 86 ° F in the winter.

The shell grew significantly faster during the night than the day, which suggests that there may be a relationship with one of the other kind, which originated from sunlight, experts believed.

“This bivalve had a very strong dependence of the daily cycle, which suggests that it may have had photosymbionts,” Winter explained. “You have to have it day and night, the rhythm of the light is absorbed in the shell.”

“Overall, the quality of the data-set has allowed the authors to draw two interesting conclusions that can help to sharpen our understanding of Chalk, astrochronology, and rudist palaeobiology,” said Peter Skelton, a retired professor of palaeobiology at The Open University, and a rudist an expert unaffiliated with the new study.

The researchers hope that the find will enable them to make use of the laser method, in order to have a look at older fossils, in order to get a better sense of what the planet was like tens of millions of years ago.

The dinosaurs had become extinct 65 million years ago by an asteroid that hit Earth in what is now the Yucatan Peninsula in Mexico. It has not only wiped out the dinosaurs, but the killing of as many as 75 percent of all species on the planet. It may be too acidic the earth’s oceans, after the impact, according to a new study published in the October, 2019.


Another study, published in September of 2019, compared to the impact of the natural disaster, according to the power of 10 billion nuclear bombs.
