Fishteacher73 Posted January 19, 2005 Report Share Posted January 19, 2005 I am looking for a good source of info on early invert. life. i've read Gould's Burgess Shale, but it really does not get into much of the biology of the organisms out there. Anyone got any sources or ideas about these guys? I have a fascination with marine corals and the argument of what actually constitutes an organsim in these (ie, is it the whole colony or just the polyps?). Thanks for any ideas.

Tormod Posted January 19, 2005 Report Share Posted January 19, 2005 Help...what does "invert. life" mean? Invertebrate? Quote Link to comment Share on other sites More sharing options...
Fishteacher73 Posted January 19, 2005 Author Report Share Posted January 19, 2005 Yes, sorry...invertebrate...too used to the slang of my biology dorks and reef people.. Quote Link to comment Share on other sites More sharing options...
MortenS Posted February 3, 2005 Report Share Posted February 3, 2005 Early invertebrate life: Can I suggest the following book: Invertebrate Palaeontology and Evolution by E.N.K. Clarkson. It should be available from various online bookstores (Amazon, B&N etc). Most books on palaentology seem to focus mostly on structure, and this book is no exception. It does contain some information on biology as well. I would probably get a book on living invertebrates as well, to complement the paleontology textbook.

maddog Posted February 4, 2005 Report Share Posted February 4, 2005 I would like to know any source of info paleomicrobiology... I barely got that out. That is study of ancient microbes and how they evolved.... ;) Maddog Quote Link to comment Share on other sites More sharing options...
Fishteacher73 Posted February 4, 2005 Author Report Share Posted February 4, 2005 Thanks Morten. I will need to check it out. I've read The Burgess Shale by Gould, and it was interesting, but not a greatd deal of scientific info in it, more of a history of the site and evolution of the theories around the organisms found there. As for current info, most of mine has been based on the marine ornamental trade (Reef tanks) because that is what I tend to focus on and that realm has the most acessable books (Finding and $$$).

That is study of ancient microbes and how they evolved.... :D Maddog I really have not seen to much info on that. I'm sure you could find some journal articles, but I do not know of any texts. I think most of the inferences on ancient microbes is through study of current microbes and their DNA. There just is not that much that fossilizes of a single cell organism with no cruchy parts... :D There are some deposital evidence (Stomalites) but I do not think that the actual fossil is the organism, but just calcarious secretions.

MortenS Posted February 4, 2005 Report Share Posted February 4, 2005 Here is a rather nice review that summarize both geological and paleontological evidence, as well as points out areas where scientists have not reached a consensus. It also provides some speculation that might provide fuel for further research.The habitat and nature of early life Some other articles that goes more into detail: Molecular fossils:Archean Molecular Fossils and the Early Rise of EukaryotesIsotopic evidence for microbial sulphate reduction in the early Archaean era Geochemistry and climateEarth's Early Atmosphere Microfossils and stromatolites:Photosynthetic microbial mats in the 3,416-Myr-old oceanFilamentous microfossils in a 3,235-million-year-old volcanogenic massive sulphide deposit Stromatolites 3,400-3,500 Myr old from the North Pole area, Western AustraliaMicrofossils from the Neoarchean Campbell Group, Griqualand West Sequence of the Transvaal Supergroup, and their paleoenvironmental and evolutionary implications.

(Abstract only) Phylogenetic studies and classificationProtein Phylogenies and Signature Sequences: A Reappraisal of Evolutionary Relationships among Archaebacteria, Eubacteria, and EukaryotesTowards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya. When looking at ancient microbiology, it doesn't hurt to know a bit about the present microbiology:The Prokaryoteshttp://141.150.157.117:8080/prokPUB/index.htm This is just a few sources on microbial fossils and reconstruction of the evolution of prokaryotes. Its no problem in digging up more references to work in this area. A good place to start searching is: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed and using search words like: Archean, Proterozoic, prokaryote phylogeny, prokaryote evolution, stromatolites, microfossils Quote Link to comment Share on other sites More sharing options...
