I missed this first time around. News from 2013. Has there been anything similar before or since?

Scientists produce cloned embryos of extinct frog.

The bizarre gastric-brooding frog, Rheobatrachus silus — which uniquely swallowed its eggs, brooded its young in its stomach and gave birth through its mouth — became extinct in 1983.

But the Lazarus Project team has been able to recover cell nuclei from tissues collected in the 1970s and kept for 40 years in a conventional deep freezer. The “de-extinction” project aims to bring the frog back to life.

In repeated experiments over five years, the researchers used a laboratory technique known as somatic cell nuclear transfer. They took fresh donor eggs from the distantly related Great Barred Frog, Mixophyes fasciolatus, inactivated the egg nuclei and replaced them with dead nuclei from the extinct frog. Some of the eggs spontaneously began to divide and grow to early embryo stage — a tiny ball of many living cells.

Although none of the embryos survived beyond a few days

saw a tv program about this a few weeks ago. they only can get the team together for short periods. so it isn’t a full time project.

there was a doco of it up on iView a while back which was worth a watch.

that was probably it.

Seems to be no longer up, unfortunately.

More … Three years later.

“This year the researchers took a step back and discovered they had a problem with their transfer process. They trialled the process on two still-living species and hit the same snag as when they tried to clone the extinct.”

I wonder if eventually we could revive extinct species just from their genetic code.
We sequence the entire thing and artificially recreate the DNA and place it in a blank eggs/embryo/seed

I think so. It may take a bit of trial and error to get the methylation (ie. epigenetics) correct. The epigenetics would have to be read off a similar species.
