Here’s what gives me pause: the accessory laminae in theSaurophaganaxholotype are pretty much dead ringers for the spinoprezyg laminae (SPRLs) in thegiant Oklahoma apatosaurine. I didn’t figure that out, Andy Danison did, and it’s one of those things that has just kept growing and ...
You need a tractable way to get started, to organize the things you’re learning, and to create a little structure for yourself. My recommendation: do a little project, with the emphasis onlittle. Anyone can do this, in any area of human activity. Maybe your project will be creating a ...
Bottom front corner bumped, pages a little browned as usual, else near fine in the near fine printed acetate jacket with a tiny chip and tear at the spine heel, and another minuscule chip at the top flap fold. An exemplary copy overall of a book seldom encountered in nice condition. $...
Random passers-by probably thought this was some kind of bat/demon/Lovecraftian horror, but those in the know would recognize it as the human sphenoid bone in anterior view. Tess writes, “Full disclosure, I did print out a template and used toothpicks for the outline.” Here’s her temp...
I don’t hate these; these days I have a hard time getting agitated about anything that brings someone else joy, as long as it’s not hurting anyone. And if you’re looking to decorate for Halloween, you could do a lot worse — these are at least recognizable human skulls, unlike the...
Wedel, Mathew J., and Michael P. Taylor. 2013. Neural spine bifurcation in sauropod dinosaurs of the Morrison Formation: ontogenetic and phylogenetic implications. Palarch’s Journal of Vertebrate Palaeontology 10(1): 1-34. doi:10.59350/z9gbg-qka93 ...
Assuming the scale bar is supposed to be 1 meter (and not 20 meters or 2.0 meters as it is labeled) yields a summed cervical length of 13.4 meters, a summed dorsal length of 3.39 meters, and a cervical/dorsal ratio of 3.96–all admirably close, off by no more than 4cm across 16+...
but it hurts my head. Most teeth I know of have their convex faces outward, like human incisors and tyrannosaur premaxillary teeth. Plus, instinctively it seems like predator teeth should curve toward the back of the mouth, but with their flat labial faces and convex lingual faces, most shar...
The multiverse of computationally generated analyses covered asmallerrange than the spread discovered by human teams! Whatever human analysis teams were doing — choosing different possible statistical frameworks, model forms, data recoding, outlier exclusion, etc — it produced more widely varying output...
A final piece before we get back to Dolly: we know from lots of anecdotal observations, and some actual experiments, that air-filled bones have to stay connected to the outside to form in the first place, and to stay healthy afterward. This is true of both human sinuses and postcranial...
