We summarize information concerning Recent and Pleistocene-Holocene Uruguayan sand dollars (Mellitidae), as well as Miocene taxa (Monophorasteridae). Recent and Pleistocene-Holocene species (Encope emarginata, Mellita quinquiesperforata, and Leodia sexisperforata) are at their southernmost limits of distribution, with only E. emarginata recorded further south than Uruguay. Lower temperatures to...

Many larvae and other plankton have complex and variable morphologies of unknown functional significance. We experimentally and theoretically investigated the functional consequences of the complex morphologies of larval sand dollars, Dendraster excentricus (Eschscholtz), for hydrodynamic interactions between swimming and turbulent water motion. Vertical shearing flows (horizontal gradients of ...

An intrathoracic gossypiboma is a rare condition. We are reporting a case of intrathoracicgossypiboma which was misdiagnosed as a recurrent aspergilloma. In our patient, the gossypiboma manifested as a pleural- based extra pulmonary mass which had a large contact area with the pleura and it displayed an extra pulmonary location. A retained surgical swab (gossypiboma) is a rare but an important ...
