Trace fossil evidence of coral-inhabiting crabs (Cryptochiridae)

[Plantguy]

Curiosity question for any of you who may have some Plio-Pleistocene coral samples from Florida or possibly elsewhere... 

 

I'm wondering if any of you knowingly or unknowingly have one of these crescent shaped fossil crab burrows as shown below?

 

I was checking with Roger Portell at FL Museum of Nat History about some other types of traces/things and he shared a recent article he coauthored.

Trace fossil evidence of coral-inhabiting crabs (Cryptochiridae) and its implications for growth and paleobiogeography

've begun going thru all my samples and cant find that I have an example yet. Darn it! I'm wondering if any of you have one of these little traces? If yes, I'd love to see a photo! Here's a shot of them in Figure 2 from his article but they have other figures with other types of corals and locales..

Joe (Fruitbat) has linked the document in his reference section in Scientific American.  Way to go Joe!

I see its also in Nature.com as well--not sure if there is any difference-I do like the zoom feature they have for the figures.

Hoping one of you has one!
