@dmcediacaran.bsky.socialThis #FossilFriday I wanted to share a teaser for some work coming out this week on how best to go about retrodeforming our #Ediacaran fossils here in Newfoundland. These are from another new fossil site with a lot of tectonic compression that changes the appearance of the fossils needing retrodef.

@ausarchosaur.bsky.socialIn the Sao Khua Formation of Thailand, sauropod remains have been found associated with both ziphodont theropod teeth and conical spinosaurid teeth, suggesting both fed on sauropods. Sadly, neither Siamotyrannus nor Siamosaurus are known from a whole lot (the latter just from teeth). #FossilFriday

@andersonmineral.bsky.socialThe skull of one of the largest dinosaurs, Patagotitan!! A close up look at what is at the top of a very long neck. #FossilFridayโ๏ธ๐งช๐ฆ
@daverodland.bsky.socialOh, also, #FossilFriday
@tomsharperocks.bsky.social#FossilFriday: the displaced vertebrae at the base of the unexpectedly long neck of the Plesiosaurus discovered by Mary Anning in 1823 which caused some discussion at the time, and Henry De la Beche's fun interpretation of how the bones came to be displaced in his 1829-31 lithograph Duria antiquior.
@richardfallon.bsky.socialAmazing what you find on Saatchi Art. The extinct giant salamander Andrias scheuchzeri, the famous Homo diluvii testis and star of War with the Newts, now finds its way to contemporary Surrealist art in a 2014 work by Czech painter Rudolf Janรกk. #FossilFriday?
