Episode 20: Sexy dinosaurs!

March 5, 2013

Did we get your attention?  Join us for episode 20, where we talk to Jon Tennant (@protohedgehog), PhD student in paleontology at Imperial College, London about the ins-and-outs of the Jurassic-Cretaceous extinction, feathers and sexual dimorphism in dinosaurs, and how the “terrible lizards” got freaky!

Science-wise, the Knell et al. paper on detecting sexual selection from the fossil record can be found here, but several of the authors have blogged about it as well (Darren Naish at Scientific American, and Dave Hone at the Guardian). If, however, you want to go straight for the good stuff, check out Buzzfeed’s top NSFW dinosaur images

In addition, a response to the Knell et al. paper prompted our very own Rafael Maia to start blogging, with this excellent post entitled ‘Understanding the sexual selection we cannot see‘. Go check it out!

    You guys were talking about Cretaceous amber and biting insects and what you might find in them, so I thought I should leave just a sample platter of links here for your perusal…

    Paleohaemoproteus burmacis gen. n., sp. n. (Haemospororida: Plasmodiidae) from an Early Cretaceous biting midge (Diptera: Ceratopogonidae).

    Evidence of vector-borne disease of Early Cretaceous reptiles.

    Early Cretaceous trypanosomatids associated with fossil sand fly larvae in Burmese amber

    Lutzomyia adiketis sp. n. (Diptera: Phlebotomidae), a vector of Paleoleishmania neotropicum sp. n. (Kinetoplastida: Trypanosomatidae) in Dominican amber

    Also, on the prehensile dinosaur wang, that was the subject of one of C.M. Kosemen’s illustration in “All Yesterdays”.

    Here’s an idea for a sexy trace fossil: if a Spinosaurus’ schlong was dragged through the dirt, I suspect it may resemble something that looked like a glacial moraine.
