Where are the images sourced from? I'm not necessarily against AI illustrations... but making recreations of extinct species right is a tricky multidisciplinary thing, not something AI can do well without a great deal of tweaking and domain-specific knowledge. If it's AI, it would be good to know the prompts and what specific features they mention, because then we'd know the actual methodology.
Edit: Don't waste your time scrolling. The images are a complete joke. There are some bad recreations out there - these are worse than you can imagine.
