The Dark Master requested: “Maybe a speculative Placodont or choristoderes. Feel free to do anything, just if they had continued to evolve and survive”
In a slightly different timeline to our own, the last surviving choristodere Lazarussuchus didn’t go extinct during the Miocene. Instead it survived in European waterways until the Messinian salinity crisis, and dispersed down into northern Africa when the Strait of Gibraltar closed up.
During one of the “Green Sahara” humid periods its descendants made their way further south, and now Keravnodraco dominusobscuri is found in lakes and rivers throughout the rainforests of West and Central Africa.
About 1m long (3’3″), it hunts small fish and aquatic invertebrates in dark murky waters, using a unique set of electrogenic organs in its elongated neck to actively sense the bioelectric fields of prey in dark murky waters – and also generating electric shocks that can stun its targets or deter predators.
