I found myself in need of an analogy to describe the shape of these structures, and I settled on “squirrel tails” because Bartholomew and Lewis’ cross sections of the features reminded me of how a squirrel drapes its tail over its body and head. I find this model complicated to look at compared to a nice set of colorful thrust imbricates, but I think it does contain a legitimate squirrel tail-type structure with upright and overturned limbs of comparable length. Based on observations from a couple of other models, I think the overturned limb might develop through tightening and stretching of an early fold at the trailing edge of the future squirrel tail block.
