First Record of Soft Tissue Preservation in the Upper Devonian of Poland
Soft tissue preservation is reported from Upper Devonian deposits of the Holy Cross Mountains, central Poland, for the first time. The preserved soft tissues are muscles associated with arthropod cuticle fragments. The muscles are phosphatized with variable states of preservation. Well-preserved specimens display the typical banding of striated muscles. Other muscle fragments are highly degrade...
متن کاملOutcome of Incus Interposition after Preservation in Soft Tissue
Introduction: The lenticular process of the incus succumbs to necrosis in chronic otitis media. Few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. Nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. This study was carried out to demonstr...
متن کاملOldest coelacanth, from the Early Devonian of Australia.
Coelacanths are well-known sarcopterygian (lobe-finned) fishes, which together with lungfishes are the closest extant relatives of land vertebrates (tetrapods). Coelacanths have both living representatives and a rich fossil record, but lack fossils older than the late Middle Devonian (385-390 Myr ago), conflicting with current phylogenies implying coelacanths diverged from other sarcopterygians...
متن کاملSoft Tissue Preservation in Terrestrial Mesozoic Vertebrates
Exceptionally preserved fossils—i.e., those that retain, in somemanner, labile components of organisms that are normally degraded far too quickly to enter the fossil record—hold the greatest potential for understanding aspects of the biology of long-extinct animals and are the best targets for the search for endogenous biomolecules. Yet the modes of preservation of these labile components, and ...
