... a depositional context. The simple Y-, J-, and I-shaped, vertical to inclined burrows referred to as Psilonichnus include three distinct ichnospecies– P. tubiformis , P. upsilon , and P. lutimuratus . Each can be attributed to either of two decapod crustacean progenitors, thalassinoid mud shrimp, or ocypodid...

... MacEachern, whom I cordially acknowledge. Present-day burrows of Psilonichnus tubiformis have been attributed to Upogebia affarmis ( Fürsich 1981 ) but may also have been excavated by a thalassinidean decapod somewhat like Upogebia ( Frey et al. 1984 ). Modern examples of Psilonichnus upsilon...
