ya i heard about this. i was interested in exploring africa because i heard of several cryptids there from cat sized tunnel web spiders to neoplurodon type things. I did a lot of reading and found the story of some guy finding these things for the first time. it makes me wonder what else could be out there.

Them giant spiders, giant tapir and giant bipedal ape with spikes on the back, are probably safest bets. There are precedent of similar creatures both extinct and existing. Flying carnivorous dinosaur is tentative, but if it transitioned to fully warm-blooded like birds - I don't see why Central Africa couldn't support such a creature. Giant carnivorous eel-like fishes probably exist too. I doubt T-rex or large dinosaurs are still a thing though as their bodies required higher levels of atmosphere oxygen to exist.
