Many FFM's know of Niles Eldredge by way of the recently erected genus of Eldregeops and particularly Eldregeops rana. (Penn Dixie site and others.) Eldrege studied the then Phacops rana. LINK below. The book's subtitle is “ THE GREAT DEBATE AT THE HIGH TABLE OF EVOLUTIONARY THEORY”. I didn't know of “THE GREAT DEBATE' and am taking the account as the history and “state of the science” of evolutionary theory. Published in 1995, there is apparently much subsequent development of the theory and science involved. Cheers , G Systematics and evolution of Phacops rana (Green, 1832) and Phacops iowensis Delo, 1935 (Trilobita) from the Middle Devonian of North America. Bulletin of the AMNH ; v. 147, article 2 Eldredge, Niles URI: http://hdl.handle.net/2246/1095 Date: 1972

Hey everyone, I recently got back to my project on theropod evolution. Just to know, between the family Dromaeosauridae and the stem deinonychosaurian Caihong juji, which one is more closely related (cladistically) to Avialae? Thanks in advance. -Christian

Hey everyone Would anyone here know of the most recent and up-to-date cladogram for the entire Theropoda? In what paper does it appear in? Thanks for the help. -Christian

here What NOT to expect: it's not a "pictorial atlas of...",far from it. Expect character matrices,cladograms. Any part dealing with ptychopariids might have been published already ,BTW

Is there a way to define fish without calling myself one?
Gelatinous squid posted a topic in General Fossil Discussion
Is it possible that not all the creatures we call fish are actually fish? -
2011_ZelenitskyRSL+aves{cladisticstheropod_olfaction.pdf Read this one. I found it informative*,and the methodology is sound. The proxy for the "sense of smell" is clearly explained Now I'm interested in the precise way smell is used by predators in general.. *in particular the short remark about sphenethmoid preservation

Around 1967 Jefferies launched his preliminary ideas on "calcichordates". Many echinoderm specialists are not convinced by his ideas. But: his interpretation of functional morphology makes sense,and his plate nomenclature has been taken onboard by at least some non-adherents of his theory. Although NOT commonly found,in some parts they can be a significant part of the paleofauna. Time to meet a fascinating group of animals!
