Terrestrial Soldier Crab (Coenobita Clypeatus, Fabricius 1787) And Cerion Spp. (Röding 1798) Shell Relationship On San Salvador Island, Bahamas, Harley Hunt
Biology Theses
The Caribbean terrestrial soldier crab, Coenobita clypeatus(Fabricius 1787), coexist and utilize the shells of numerous species of land and marine gastropods. Soldier crabs rely on gastropod shells for protection as the crabs have a soft abdomen, leaving them vulnerable for predation and desiccation, threatening their survival. This creates a strong pressure to obtain well-fitting shells that provide adequate protection against water loss. Cerion of Röding (1798) shells are one of the most commonly used shells among living colonies of C. clypeatuson San Salvador Island. This study is interested in the frequency of shell use by C. clypeatus crabs …
Taphonomy Of Late Jurassic (Tithonian) Morrison Formation Apatosaurus Sp. Vertebrae Found Associated With Teeth From Allosaurus Sp. And Ceratosaurus Sp., And Body Size Extrapolation From The Associated Theropod Teeth., Greg C. Agyan
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
An Apatosaurus sp. locality from Dinosaur National Monument designated DNM-15 was excavated in 1985, and associated with two Allosaurus teeth and one Ceratosaurus tooth that were near one of the caudal vertebrae. The Ceratosaurus tooth was buried between an overlying rib and that same caudal vertebra. The caudal vertebrae of the DNM-15 Apatosaurus were intact and articulated, but the anterior skeleton was mostly absent, with a row of articulated sacral vertebrae in close association with a femur. Two other Allosaurus teeth were reported near the preserved ilium of the Apatosaurus, but they could not be located in the collections. …

Curation Techniques Of Small-Sized Natural History Specimens: A Collection Of Microfossils., Zachary V Biven-Leslie, Guillermo W. Rougier
Undergraduate Arts and Research Showcase
Small-sized fossil specimens are challenging regarding safety, storage and traceability of information. A recent collection of several hundred minute early mammalian teeth and jaws (most about 1mm) made impossible the standard practices of specimen numbering. A reliable association of the specimen and the collection number is the minimum required, however, a number of other data easily recoverable from the specimen/curating material is desirable. Geological provenance, locality, systematic and anatomical ID, collector, year, etc. is often included if possible. Use of the specimen is expected to be on the order of hundreds of years, manipulated by investigators, transported, and stored in …
