Bear with me, I was gonna do a proper photoshop to better illustrate what I was thinking, but opted to go more... rough... with it. This is not to scale, etc - and just hypothetical on my end.
What if the old "Amber Mine" coaster idea returned - starting the coaster slower, going into a "mountain" Disney Everest style, with stunning amber caves - when suddenly the coaster becomes more thrill oriented as volcanic activity occurs.
The coaster could then escape into the water, with a near miss with a Mosasaurus, and then back into the jungle. There could be some other themed elements, like one or two more dino AA's, and perhaps geysers or geothermal activity/ lighting effects.
Again, this is rough -- blue indicates tracks, yellow would be tunnels/openings.
