Perfectly preserved babyÂCrocodilaemus fossil Âfound at Brunn in the Solnhofen limestone beds in Germany was set to go on public display at the BÃrgermeister-MÃller-Museum in Solnhofen (but new restrictions on public gatherings in Germany have closed the museum for now). The fossil was discovered last year. Crocodilaemus (or Crocodileimus) is best known from Cerin in France, which has similar Jurassic limestone deposits. (in German)

Abstract only for now...
Tetrapod life on land was the result of a lengthy process, the final steps of which resulted in full independence of amniotic tetrapods from the aquatic environment. Developmental strategies, including growth rate and the attainment of sexual maturity, played a major role in this transition. Early amniotes, such as Ophiacodon, tended to reach sexual maturity in a year while most non-amniotic Paleozoic tetrapods (including Devonian tetrapods and temnospondyls) became adult after 3 to 11 years. This ontogenetic transition is accompanied by a drastic change in growth rate and bone microstructure suggesting faster growth dynamics in early amniotes than in Devonian tetrapods and temnospondyls. Was the acquisition of a faster development (earlier sexual maturity and faster growth rate) a drastic evolutionary event or an extended process over geological time? To answer this question, the limb bone histology of two Early Permian (i.e. 270-290 million-year-old) stem-amniote seymouriamorphs, Seymouria sanjuanensis and Discosauriscus austriacus, were investigated. We used three-dimensional bone paleohistology based on propagation phase-contrast synchrotron microtomography. Both seymouriamorphs display relatively fast bone growth and dynamics (even though cyclic in the humerus of D. austriacus). This significantly contrasts with the slow primary bone deposition encountered in the stylopods of temnospondyls and Devonian (i.e. 360 million-year-old) stem tetrapods of similar sizes. On the basis of skeletochronological data, the seymouriamorph D. austriacus retained a long pre-reproductive period as observed in Devonian tetrapods and most temnospondyls. The combination of characteristics (faster growth rate but long pre-reproductive period) suggests that the shift towards an amniotic developmental strategy was an extended process in the evolutionary history of amniotes.

Corrections...
In theÂlast news post IÂmade a typo in the subject line (s/b Ankylosaur osteoderms) and included an ICE press release dated 2014 about smuggled dinosaur fossils. The ICE item had been posted on a Twitter feed last week and I copied the link for my records but didn't label it by date. In putting together the news list, I inadvertently included it in a set of recent stories. This flub apparently caused some confusion. My apologies. No harm done I hope... It's still notable for the record (with photos) in the DML archive--the official release was not posted to the DML at the time it appears. All the other stories were more current.
