In the remains of a primitive fish found in Orkney, the earlier science-known “babies” were discovered.
The unborn embryos found in the fossil of South Ronaldsay dating back to 385 million years ago are said to have been found by researchers.
The Watsonosteus fletti was born into young people, now a member of the collection of the National Museums of Scotland.
When scientists saw the cut through rocks that had formed in mid-Devonian times, the minuscule remains were found.
The fossilised embryos from Australia are at least three million years older than the previous record holder.
In the journal, Paleontology, details of the discovery were written.
Mike Newman, the lead author of the study, told BBC Radio Orkney: “We just only divided randomly and we saw what the bones created, while they were fossilised.
“We found intestine material inside, but then these peculiar, very thin, small skeletons. It became clear that they were really adult juveniles when we looked into the specifics of these skeletons.
The fish seems to have born young people and not laid eggs.
However, though she was still pregnant, she died and sunk to the base of the lake.
Initially, scientists thought the bones may have been small fish she had eaten, but they also seem to adapt, and thus could not survive alone.
And because of a simple layered rock pattern on the bottom of the ancient lake that has a distinct-and much earlier than the Australian examples-the entire ecosystem can be assured in the dating.
You agree to know now what you want because even earlier embryos might be found in the fossil record. But these are the youngest babies remembered at least for the time being.
“More findings are likely to drive it a little more further,” says Mike Newman. “In other areas with older, identical, fossil fuel, we might even get back another 10 million years.”
According to Dr Stig Walsh from the national museums Scotland, the embryos are added to a long list of Scottish fossil firsts.
“Scooslavia and the Islands have a fantastic record of fossils,” he said: “Orkney, in particular, is of major importance.
“We seem to have the first of all. We got the first animal on earth. The first animal backbone that landed on earth. We have the earliest land ecosystem. And I said, ‘Yes when I learned what they had figured out! We have another. “We have another.
