Fossil discoveries in Scotland are challenging long-held beliefs about the growth and development of early mammals.

Analysts recently revealed that mammals living alongside dinosaurs likely developed slowly, but they had a larger lifespan than they do today. The researchers shared this opinion while studying fossils that have been found on the Isle of Skye.. It’s a mouse-sized mammal that lived approximately 166 million years ago.The analysts used X-ray technology to scan the specimens and then examined growth rings in the species’ teeth.

“Mammals have the biggest range of body sizes. They’re living in the most habitats. They have the widest range of ecologies. And so everybody’s asking, Why? Of course, to understand that, we have to understand where their unique biology comes from. So this is a piece of that puzzle,” she toldoffer a lot of insights into the anatomy of the creature and shed light on the speed at which it grew and matured.

This implies, according to the researchers, that these mammals weaned at a much younger age. This suggests that despite their slow growth, they weaned at a similar age to larger mammals, such as the brush-tailed possum or Barbary macaque.
