intriguing
and
dynamic conversations concerning thin section
petrography and interpretations were held with J.
Carew, F. Ricart,W.Goter and P. Bretsky, which
were most helpful. The thin sections of coral provided by F. Ricart were of outstanding help. David
Van Voorhis is thanked for his great patience in
counting of tracks.
Critical review of the manuscript by R. L.
Fleischer, S. Katz, and H. Clark is appreciated.
