Among other things, Allis was involved in the founding of the Journal of Morphology. His resources helped keep the journal solvent during its first few decades.

100+ y.o. tractor @ Henry Ford with a fishy connection. Edward Phelps Allis Jr., one of the great comparative anatomists of the last century, enjoyed substantial financial support as the son of E. P. Allis Sr., founder of a manufacturing company specialized in industrial and agricultural equipment.

Brown striped Bawitius

Brown striped Bawitius

Another interesting fish from the Kem Kem - Bawitius! This is a 3m-long bichir, a group of fish I wasn't familiar with until starting this piece. Today, members of this group don't get more than a meter in length, and are apparently popular in aquariums!

I always look for paleo books at used books stores. Thereโ€™s an awesome one in Ann Arbor (Dawn Trader) that has had some great finds!

A view of the headshield of Megalograptus, preserved as reddish-brown cuticle on a pale grey rock. The headshield is generally equilateral in shape, with a rounded front bearing small spiny projections. A pair of round eyes are also located at the front of the head. The surface of the headshield is curved in dense, pustule-like scales.

A fossil of the second appendage of Megalograptus, preserved as dark cuticle on a light grey rock. The appendage is short with robust spines coming off of it.

One of the earliest large predatory eurypterids, Megalograptus, for #FossilFriday. Megalograptus is known from abundant - and very unusual - material from the Ordovician of #Ohio, affording an important insight into the morphology of this rather bizarre species. โš’๏ธ๐Ÿงช

Ok, my first post on BlueSky...this was inside the AMNH Fossil Fish collections back in September as I was preparing my fish lectures for the AMNH/RGGS Vertebrate Paleobiology course. I'm honored to have been invited back to teach it for the third time (also 2019 & 2022).

Some AMNH display specimens with UMMP connections. Pretty sure this Kannemeyeria is a cast of UMMP VP 14530. The Dimetrodon skeleton was collected by E.C. Case in 1906, a year before he started at the University of Michigan. Case would later go on to be UMMP's first director. #FossilFriday

Go my Bothriolepis... This year's fish pecan pie! Bothriolepis was a peculiar-looking placoderm from the Devonian period or the Paleozoic. It had two long pointed pectoral fins and silly little eyes on top of its head.
