I don't have access; I found out via this science news service http://www.wissenschaft.de/wissen/news/273108.html (in German) which mentions that sauropods may have _actually eaten_ stones for minerals.

If not for a gastric mill, then perhaps ingestion was incidental. Are any coproliths known to be from sauropods, and if so, are such stones present in them?
