I won't go into everything the site says about dating, but it does say:
" Roman authors wrote about showers of stones falling from the sky and terrifying the populace. In 205 b.c., because of these events, the Senate ordered that a conical meteorite known as the Needle of Cybele (which had been worshipped in Asia Minor in connection with the fertility goddess Cybele) be brought to Rome. On the rim of the largest crater, named Tüttensee, archaeologists have found Roman relics from about a.d. 200. This, in addition to the heated coins from the late Roman period we found at the Chiemgau impact site, lead us to favor this early date."
