The bones of the Castelnau giant were studied at the University of Montpellier and examined by M. Sabatier, professor of Zoology, at the University of Montpellier, and M. Delage, professor of paleontology at the University of Montpellier, in addition to other anatomists.
The Shamrock Shake was first introduced in 1970. Rogers Merchandising in Chicago created the shake. Initially, the shake was lemon/lime flavored with vanilla ice cream, lemon/lime sherbet, and vanilla syrup. By 1973, the shake was merely a green colored vanilla shake, eliminating the lemon/lime sherbet.
For St. Patrick's Day in 2010 and 2011, on the banks of the dyed-green Chicago River, McDonald's produced the World's Largest Shamrock Shake and poured its limey green fluid into the river. That promotion also supports Ronald McDonald House and has raised $10,000 per year.
