I've seen them in docs and in books but never in a complete form. Usually it's a graphic of a certain branch to elaborate on the subject or species of topic, but I was wondering if there were websites or info that was encyclopedic and all encompassing as we know it so far. I've tried to look around for it on the web but never came upon anything beyond WIKI (LOL), but in todays modern world I would have thought there would be a clear and informative and concise website with an aggregated collection of what science knows to this point. You can go on a gazillion websites and order any

Apes' inner ears could hide clues to evolutionary history of hominoids
msantix posted a topic in Fossil News
A study looked at the morphology of the inner ears of living and extinct hominoids (living hominoids includes humans, chimpanzees, orangutans, gorillas etc). Using a 3D imaging technique, the team were able to capture the complex shape of the inner ear cavities among 27 species of monkeys and apes including humans, the extinct ape Oreopithecus & the fossil hominim Australopithecus. The findings showed that the shape of these structures reflected the relationship between the species and not how they moved. The findings confirmed that the inner ear of Australopithecus resembled l-

Reef-building coral exhibiting 'disaster traits' akin to the last major extinction event
msantix posted a topic in Fossil News
A new study shows that stony corals, which provide food and shelter for almost a quarter of all ocean species, are preparing for a major extinction event. Researchers identified an increased prevalence of certain traits found with previous extinction-survival characteristics among corals. By studying the fossil record of coral skeletons, they were able to determine that corals are showing some survival traits that match the last major extinction event 66mya. These traits include an increase in deep water residence, cosmopolitan distributions, smaller colonies, non-symbiotic relati-

I've been curious about this for a long time. Nowadays, we know that oceanic trenches aren't the desolate aquatic wastelands we thought them to be, and there are animals living down there. Considering their rather extreme geologic environment I'm wondering, if it is even possible, whether they left any discernible fossil-bearing facies in the record at all? Or just discernible facies, period. A cursory search yielded no results for me. As far as I can see, sedimentation rates would be low, and any newly-formed sedimentary rocks would just get subducted and destroyed very quickly (

In this thread I propose to post fossils(including dubio-and pseudofossils) of uncertain affinities,OR have a very sporadic fossil record,OR might be new to members of this forum . A lot of the times this will mean fossils from Lagerstatte,so considerations/musings on taphonomy will be in these articles as well Kinorhynchids(Cycloneuralia ,China): ZhangHuaqScientificReports.pdf Nematoda (age:ordovician/China): balin2013nematoda.pdf

Species and Speciation in the Fossil Record, Chapter: 11
oilshale posted a topic in Fossil Literature
Wiliam E. Bemis: "This paper briefly explores concepts of species of “fishes” in the fossil record . For an evolutionary biologist also interested in systematics, it is impossible to study any fossil species without careful study of and reference to extant species. Thus, this paper is informed by anatomical comparisons to extant fishes as well as their nomenclatural history, as exemplified by the Catalog of Fishes (Eschmeyer, 1998a, 2015), with the goal being synthesis of neontological and paleontological perspectives. The enormous literature on species concepts, speciation and systematic- 1 reply
