bezoar - new part name for ES, Mamm collections

[Nicole-Ridgwell-NMMNHS]

Goal
Catalog fossil material.

Context
I'm not sure if this new part is needed or not. Bezoar probably fits under the definition of trace fossil, but I haven't seen it addressed anywhere in the scientific literature. Do any modern collections have these? How have they been handled?

Table
https://arctos.database.museum/info/ctDocumentation.cfm?table=ctspecimen_part_name

Value
bezoar

Definition
a mass found trapped in the gastrointestinal system (https://en.wikipedia.org/wiki/Bezoar)

Collection type
ES, Mamm (any others?)

Part tissue flag
no

How cool - a fossil bezoar! How would you handle this, with ID = vertebrate and bezoar = part, or Identification = bezoar, and part = bezoar, with part attributes to describe what it is made of? Sometimes these are hair, correct, and other times other types of indigestible material. It would be good to have a way to use both part attributes and specimen attributes as descriptors.

Bezoar is very rarely used for fossils. This article is most comprehensive: https://doi.org/10.1016/j.ijpp.2019.06.009

"Bezoars, or bezoar stones, are a particular kind of patho-gastrolith (see Vallon et al., 2012) formed in the gastrointestinal tract of mammals, including humans, reptiles, birds and fishes (Sameiro and Barroso, 2013). They are very common in ruminant (e.g., goat, deer, sheep, antelope, horse, tapir and guanaco), and their formation is linked to the swallowing of hair, sedimentary particles, vegetable fibers and seeds, among other substances (Bullock, 1929; Elgood, 1935; Mikaili and Shayegh, 2011). These structures form through lithiasis; the generation of a solid bioinorganic structure in an aqueous medium due to the precipitation of mineral layers around a nucleus (Simkiss and Wilbur, 1989). Dimensions and shapes of the bezoars are variable, and in some cases, they can obstruct and compress the intestinal walls causing death of the animal (Bonacic, 1992)."

Bezoars can also be considered a trace fossil.

@Nicole-Ridgwell-NMMNHS given the above, how would you like to treat this?

I suggest using gastrolith with bezoar in remark for now - the discussion about what is a trace fossil can take place elsewhere?

Yes, let's just do that
