I’ve updated the Illustration.

Seems like they got it straight from the university press release here. I guess we can cut them some slack for using a bit of AI given the recent job losses at that university. They are reported to have lost around 4000 full time staff places in the last year, part of Australia’s recent cut backs to universities that don’t get much international reporting. That’s may hurt their ability to do quality research. Professor Archer noted that "quite clearly, from the many fascinating animals that we’ve already found in this deposit since 1983, we know that with more digging there will be a lot more surprises to come,”. So lets hope they continue to get support.

From the interview: The main takeaway is that humans are special, but so are birds and reptiles. So our brains are amazing, but bird brains are even as amazing. We have neurons other species do not have. But the chicken, even the chicken, they do have neurons that we don’t have. So evolution has found so many different ways to generate complex brains, not just only one direct pathway from amphibians to humans. In this case, the tree of intelligence is a tree. It’s not just a single branch.
