I'm pretty dubious about this - and your assertion down-thread that the "American alligator" hasn't evolved for 150 million years" is frankly incredible.
I don't know where you're getting your palaeontology from, but you need better sources.
I'm not terribly up to scratch on the palaeontology of wasps, though I do recall that one of the large insect-rich deposits of amber is from Dominica and is about 35 million years old, so I'm going to hypothesise that you've got the far end of a "Chinese Whisper" which started with "organisms which look like modern wasps were found in (Dominican amber) which is 35 million years old".
I know my reptile evolutionary history somewhat better. While there were undoubtedly suchiform ("crocodile shaped") Suchian reptiles (ancestors of crocodiles) around 150 million years ago, that does not mean that they're the same species as the modern American alligator. At the very least, there was a modest burst of suchian evolution in the period shortly after the Cretaceous-Palaeocene boundary extinctions, which would very likely have affected many aspects of the lives of all large organisms that survived the end-Cretaceous events. Shortage of large prey would have made dwarfism a common strategy for tens of millennia, followed by an opportunity for the suchians to become the dominant land animals. Which they would have been in competition with phorusrachid "terror-birds" and mammals. It's arguable if the mammals (about 6000 species) or the birds (nearly 10000 species) won that race.
A few years ago I had the pleasure (I'm a geologist - I have ... abnormal ... pleasures) of spending an afternoon going through the Natural History Museum's cabinets of fossil coelocanths from the Mesozoic, and comparing them with the 1960-odd specimen in the main hall of the museum. From personal observation I can assert that this famous "living fossil" has changed over the 90-odd million years during which we haven't had a fossil record for it. For a start, it's about 4 times the size of it's older relatives.
