...CALEB M. GORDON; BRIAN T. ROACH; WILLIAM G. PARKER; DEREK E. G. BRIGGS ABSTRACT Regurgitalites (fossilized regurgitates) can provide insight into the behavioral ecology and physiology of extinct species but they are rarely reported because they are difficult to identify and distinguish from...

... such material. Herein, we regard coleoids with an opportunistic diet as the most likely producers of the aptychi-bearing regurgitalites. This is based on finds of aptychi in the stomachs of the two coleoids Plesioteuthis and Trachyteuthis. They were likely fast, highly manoeuvrable swimmers. Both share a strong...

... predation. Using such angular shell fragments as a predation proxy, we analyze data from 57 European Paleozoic localities spanning the Ordovician through the Mississippian. Our results reveal a significant increase in angular shell fragments (either occurring as isolated valves or present in regurgitalites...

... referable to lissamphibians, including elements of at least one small frog (possibly a tadpole) and possibly the smallest reported salamander specimen from the formation. Chemical and taphonomic characters suggest that the specimen is a regurgitalite, the first from both the Morrison Formation...

...Fig. 3. Visual summary of regurgitalites from the Egg Mountain locality with comparison to modern diurnal raptor gastric pellets. (A) MOR 10912 regurgitalite, consisting of three Alphadon halleyi , represented largely by cranial elements and broken, digested postcrania. (B) MOR 10913...

...Fig. 15. Possible regurgitalites from the Kimmeridgian–Tithonian lithographic limestone of the Causse Méjean. (a) Possible regurgitalite, fossiliferous heap composed of echinoid remains (Hemicidaroida indet.) including fragments of Aristotle’s lantern (Ar.), plates (Pl.) with perforated...

... (1992) first coined the term bromalite to encompass specimens representing digestive contents that had either been regurgitated (regurgitalites), expelled as fecal material (coprolites), or were mineralized in situ within the digestive organs following the death of an organism (cololites). Hunt...

... interpreted as regurgitalites (Freimuth et al., 2021). Given this equivocal, or at least inconsistent, evidence from other sources, the application of geochemical indicators such as Sr/Ca Ba/Ca has the potential to provide critical insight for testing the various hypotheses concerning the dietary patterns...
