Morphing still Images of development together using landmarks. 

This is an assignment I've been doing for my Developmental Biology class, where they morph together old images of developmental sequences, to create an animation of development and resurrect the older descriptive literature. 

I got Claude to write the code for this web-based morphing widget, "Embryo Morph Studio," which does a reasonable job. 

Students can find source images in the literature here and through their own research. These can be cropped, centered, and backgrounds removed in PowerPoint before exporting the image sequence. 

Image Sequences can be found below. 

Nick Hopwood has an excellent review of the normal tables, which contains some fascinating history as well as lavish illustrations.

"A history of normal plates, tables, and stages in vertebrate embryology."

His tables include a plate from Sommering's 1799 series on human embryos

Mark Hill has links to many of Franz Keibel's normal tables , including his pig series (which students like), Minot and Taylor's rabbit series, Karl Peter's sand lizard, Rugh's leopard frog , Semon's lungfish, Dean's hagfish 

More modern images of mouse embryos can be found by Theiler, the lesser hedgehog tenrec (Echinops telfairi) by Weneburg et al 2012, Arnold's squid, Kimmel et al.,'s zebrafish, Wolff and Hilbrandt's wandering spider (Cupiennius salei), Giannini et al's old-world mega bat (Rousettus amplexicaudatus - Geoffroy's rousette), and my own humble attempts at the red-backed salamander. 

More can be found in the Biodiversity Heritage Library

Lisbeth Krause has done a series of wash drawings of Ross Harrison's normal table for our favorite salamander, Ambystoma maculatum. Later axolotl tables are based on this authoritative series. See description here.  These are very old images, which were never officially published. As they have been reproduced elsewhere without copyright permission, I'm going to include them here (they are useful for our own lab work).
