Talk:Clay dog

Article shortcomings

There are some fundamental problems with this article. They include:

1. The term "clay dogs" lacks notability. It is a little-used term for calcareous concretions found in Pleistocene, typically varved, proglacial lake sediments (Berkley, 1905; Gratacap, 1884; Tarr, 1935).

2. According it usage in publications, e.g. Berkley (1905) Gratacap (1884) Sheldon (1900) and Tarr, 1935) , a "clay dog" is not a "clay formation" that has been "sculpted by river currents" from clay. The proper term for a "river sculptured," "clay formation" is either "rip-up clasts," "mud clasts," or "soft-sediment clasts" (Neuendorf et al., 2011; Knight, 2009; Zuffa, 1985).

3. Gratacap (1884) does not described clay dogs in any detail.

4. The statement that "they only occur in a few places in the world" is a false statement. In fact, they are quite common in Pleistocene, typically varved, proglacial lake sediments as discussed by Berkley (1905), Sheldon (1900), and Tarr (1935)

Given these shortcomings and lack of notability in this term, I propose the clay dog article be deleted and any useful information from references cited above be incorporated into the concretion article. Alternatively, if the consensus is not to delete this article, it can be expanded somewhat using the same articles and pictures in Wikimedia.
