There are there are many more talks deserving of recognition, including those I was unable to attend as I was in other talks (I'm told there was one on chameleons producing infrasonic sounds and being able to hear them with their feet which sounded amazing). rex also floats happily (as long as its head is up) so if that Spinosaurus reconstruction is correct and not just a rubbish, short-legged, chimeric reconstruction (personal opinion), it still isn't special in its aquatic abilities.
Not only incredibly important in terms of defining what is and isn't a joint, but realising that all the groups do it differently.
Casey Holliday and colleagues continue to produce some of the most amazing histology slices of cranial joint morphologies across reptiles and archosaurs (besides the jaw joint).Check out the website for more!įrom Gignac et al., 2016 showing diceCT utility for contrast enhanced CT scanning. The entire diceCT (sounding like dice CT, rather than dissect) symposium showing how you can obtain and utilise iodine to contrast enhance CT scanning to produce spectacular images of soft tissues in small animals (they are working on bigger animals, but diffusion is a pain without over-saturating the edges) and their utility for understanding anatomy, function and reconstructing soft tissues.The suggestion that sperm whales only have dentition on their lower jaw may be linked to helping lure squid using bioluminescence on the teeth.There were some particular highlights though amongst the rest of the science: Their works span everything from pterosaurs, birds, cats, dinosaurs, mammals, and fish. In addition to my own work, it was great seeing all of the talks of past and present lab mates (and there are now a lot from the three big groups across the universities). atrox based on musculoskeletal reconstructions. I was pleased to get the opportunity to present my work on how cat muscles scale as well as how we can use these data to reconstruct fossil taxa (in this case Panthera atrox - the North American lion, and Smilodon fatalis - sabretooth "tiger") and their soft tissues, and implications this has for the biomechanical reconstructions (keep an eye out for this paper which is currently in review).Ĭonvex hull model of P. In fact, it was 4.5 days of talks, with all starting off with some high profile speakers leading the way with plenaries, then 6 simultaneous sessions so there was something for everyone going on nearly all the time (and sometimes too much at once so things were inevitably missed). It was an incredibly busy week, a combination of a long travel (via Iceland) and lots of great talks. Remember that snakes shed wrong side out, so flipping everything back to its original orientation may help make the subtle characters more recognizable.I've just returned to work after a fabulous conference, the International Congress of Vertebrate Morphology (ICVM) 2016 in Washington DC. Cut down the chin midline and follow similar procedures as before with the head. Taking a picture and further enhancing the image contrast may help.Ħ. Turn over and lay out flat on a white surface, then dark surface. Cut down the ventral midline for a large section of the body. vent scale/s) is formed of a single scale or double scales.ĥ.
Venomous pit vipers will have several rows of single scales, while our nonvenomous species-and venomous Coralsnake-will have only rows of paired scales.Ĥ. Check the tail scalation below the vent (look for a slit opening a few inches above the tail tip). Check if the dorsal body scales are smooth, weakly keeled, or strongly keeled.ģ.
Atrox terrestrials rar skin#
Spread out and separate any skin stuck to itself if possible-roll with your fingers, apply a bit of water (or steam), even blow softly through a straw stuck down the neck-but stop when more damage is being done than helped.Ģ.
Gently retrieve the skin intact as much as possible particularly valuable are the head and tail segments. The following may be helpful toward identification:ġ. Copy Copied! Use a different Browser An accurate ID is not possible from the description and/or photo(s) provided.
