No need for you to respond. But I am not aware of any YEC theories saying fossilized reefs could not exist.
Also, I have not seen any conclusive evidence for macro-evolution (transitionary fossils). The website I referenced for you (authored by a fellow MIT grad no less www.creationscience.com) discusses both lack of transitionary fossils and DNA evidence supporting creation. And includes numerous references to other evolution and creation literature too.
