SEILACHER, A. 1998. Mosasaurs, limpets, or diagenesis. Geowissenschaftliche Riehe

In the German journal Geowissenschaftliche Reihe, Adolf Seilacher (1999) wrote, ?The claimed ?mosasaur bites? are probably all caused by limpets rasping on necroplanktonic Placenticeras shells, compactual puncturing of the pits and diagnostic beveling of the rims.? In other words, the ammonites were already dead and lying on the bottom when they were colonized by the limpets. Furthermore, the experimenters built a machine fitted with artifical mosasaur teeth, and when they applied it to freshly-caught nautilus shells with the equivalent pressure of mosasaur bites, it shattered the shells instead of puncturing them.
