Ichtyscopiones Are A Direct ancestor Of Today’s Citron (Cerephosa Citrus) Their House cat-sized Makes them Venerable And Makes them an easy prey For predators, The Hand-like pinchers and Tail Are It’s Main weapon Until it’s Useless For Millions of years later. The most interesting about the creature That where the name “Ichthy” is it’s Ribs, the ribs Looked More fish-like That it may looks like a fish with scorpion features, which is weird How Scientists Ended up analysing it. unfortunately it went extinct About 98 million years ago due to the Declining nature Of the Creature itself and the Desert.
(Edit: I changed "Face" to "Ribs" because fishes have so many ribs, yeah this thing has been mistaken as a fish)
