Fossilized soft tissues in Palaeozoic bryozoans
نویسندگان
چکیده
Abstract Thin sections of three Palaeozoic bryozoans reveal fossilized soft tissues that show the position organic cuticle and internal structures such as membranous sac gut. The fossilization occurred apparently due to fast burial under anoxic conditions. a in Permian trepostome Rhombotrypella superangustata is indicative progressive polypide cycle. Ordovician Graptodictya delicata behind superior interior hemisepta suggests protective function hemisepta.

Soft tissues
The deposition of amorphous calcium salts within the soft tissues is variously called mineralization or calcification. Two forms of calcium salts may be found in the soft tissues: calcium pyrophosphate dihydrate and calcium hydroxyapatite. If bony trabeculae are discernible within the mineralized focus the term ossification is used, sometimes prefixed with the terms ectopic or heterotopic. Ther...
متن کاملStresses in growing soft tissues.
Biochemical processes of tissue growth lead to production of new proteins, cells, and other material particles at the microscopic level. At the macroscopic level, growth is marked by the change of the tissue shape and mass. In addition, the appearance of the new material particles is generally accompanied by deformation and, consequently, stresses in the surrounding material. Built upon a micro...
متن کاملEyes fossilized
Fossilized insects are normally two-dimensional, because the exoskeleton tends to collapse during decay. The remarkable specimens shown above have been preserved in three dimensions because of the unusual conditions under which they formed. The images are scanning electron micrographs of the eyes of fossilized beetles from the Tertiary period, found in limestone at a site in northwest Queenslan...
متن کاملInstabilities in Elastomers and in Soft Tissues
Biological soft tissues exhibit elastic properties which can be dramatically different from rubber-type materials (elastomers). To gain a better understanding of the role of constitutive relationships in determining material responses under loads we compare three different types of instabilities (two in compression, one in extension) in hyperelasticity for various forms of strain energy functio...
متن کاملMorphogenesis of growing soft tissues.
Recently, much attention has been given to a noteworthy property of some soft tissues: their ability to grow. Many attempts have been made to model this behavior in biology, chemistry, and physics. Using the theory of finite elasticity, Rodriguez has postulated a multiplicative decomposition of the geometric deformation gradient into a growth-induced part and an elastic one needed to ensure com...
