A new study has shown that long-necked dinosaur species appear to have evolved into giants independently throughout time.
at Adelphi University found that many more species of sauropods, more commonly called long-necked dinosaurs, independently evolved into gigantic creatures instead of becoming progressively larger over time. The study, “The Evolution of Maximum Body Size in Sauropod Dinosaurs,” was published in the May 8 Edition of, without rival, the largest land-based creatures to ever walk on Earth. Many, like the iconic, dwarfed anything that came before them or has come since.
Microscopic study of their bones also revealed that sauropods had different growth rates, suggesting that the record-setters were metabolically distinct. This mimics the pattern observed in mammals, which rapidly grew in size after the extinction of the dinosaurs before plateauing at the huge mammoth range.

Michigan faces pushback with gun red flag law set to passMichigan could become the 20th state to pass a red flag law as the state looks for ways to address gun violence after its second mass school shooting in 15 months. The legislation has passed the Democratic-led Legislature and would be the first red flag gun legislation to pass in nearly three years. Gov. Gretchen Whitmer has said she will sign it. The law is already facing pushback on the local level. Sheriffs have shown resistance to enforcing something they believe to be unconstitutional. While the laws have seen widespread public support, an Associated Press analysis last year found they were barely used. The U.S. is on a record pace for mass shootings so far this year.
