A Reappraisal of the North American Species of the Siluro-devonian Trilobite Genus Scotiella
The type material of Scotiella Delo 1935 is redescribed and the generic diagnosis emended to include trilobites in which the anterior and median lateral glabellar furrows are both strongly and poorly defined. The genus now embraces the species Scotiella logani (Hall 1860), S. conservatrix (McLearn 1924) new combination, S. minor (M'Coy 1851), S. samsonowiczi Tomczykowa 1962b and S. opatowiensis...
متن کاملThe Trilobite: Enigma of Complexity
My goal in this presentation will be to explore the impact the discoveries of modern molecular biology have had on our understanding of the history of life on earth. I will demonstrate using a fundamental assumption of evolutionary theory, that we can know in exquisite detail, the molecular biology of one of the earliest form of metazoan life for which we have a consonant record, the Trilobite....
متن کاملThe Evolution of Trilobite Body Patterning
The good fossil record of trilobite exoskeletal anatomy and ontogeny, coupled with information on their nonbiomineralized tissues, permits analysis of how the trilobite body was organized and developed, and the various evolutionary modifications of such patterning within the group. In several respects trilobite development and form appears comparable with that which may have characterized the a...
متن کاملGroup Renaming
We study the group renaming problem, which is a natural generalization of the renaming problem. An instance of this problem consists of n processors, partitioned into m groups, each of at most g processors. Each processor knows the name of its group, which is in {1, . . . , M}. The task of each processor is to choose a new name for its group such that processors from different groups choose dif...
متن کاملThe Design of a Register Renaming Unit
Register renaming is often used to improve performance in many high-ILP processors. However, there is a lack of publications regarding register renaming hardware design. This paper presents a detailed look at one possible implementation of a register renaming unit, as well as some possible optimizations.
