Raśl, Marine reptile bones preserved in carbonate
concretions are fairly common occurrences in the Late Cretaceous Pierre Shale
of the Western Interior of North America, including the type specimen of Elasmosaurus platyurus found in 1867: http://www.oceansofkansas.com/tale-tail.html This excerpt may be of some interest to
you: ”Most of the dorsal vertebrae were enclosed in
a series of limestone concretions. The concretions may have formed where they
did as the result of carbonate ions being drawn to a locally restricted
reducing environment produced by the decay of the gut (E. Manning, pers. comm.
2001).” It is from a recent paper on the gut contents of an
elasmosaur found in the Pierre Shale of western Cicimurri, D. J. and M. J.
Everhart, 2001. An elasmosaur with stomach
contents and gastroliths from the Pierre Shale (Late Cretaceous) of An on-line version of the paper is located
here: http://www.oceansofkansas.com/plesio4.html I can send you a reprint as a .pdf file if
you would like to have it. Regards, |
