Asuka & Asuka clone?

[slk486]

I seem to remember playing a vertical shooter way back in the early 90's. I thought it was Asuka & Asuka, but looking at gameplay videos on youtube I'm not so sure. It was somewhat similar, but I don't remember the wobble screen and, even though it had dinosaur and egyptian themed levels, I remember the graphics differently than what I've seen in A & A. I remember green t-rexes that sort of shuffled in place

Anyone got a clue? Maybe I'm just remembering stuff that never was?
