Paranthropus aethiopicus is one of the fossil species that may be a "nomen dubium". The holotype specimen is Omo 18-18, a jaw that lacks any tooth crowns. What remains isn't distinct from large samples of P. boisei or P. robustus.

Many of the most important fossils of human relatives are distorted or fragmented. TM 1517 is the holotype of Paranthropus robustus, found in 1938. Here I've done a reconstruction by mirror-imaging the parts that survived fossilization and erosion.

The Holotype of Hyolithes baconi from the Ordovician Trenton Fm. in Rock County, WI. Hyolitha is a particularly enigmatic group, but was recently classified as a lophophorate, making it closely related to brachiopods. Type Collection

The new skeletal looks sweet! Ichthyovenator's tail shape would make a lot more sense with this interpretation, though its holotype still lacks many caudals so even that's not certain at the moment. I wonder how extensive the "paddle" might have been compared to Spinosaurus...

Fun fact, I actually redid a whole new Procompsognathus for the article, but ended up going with the old one anyway 'cause I liked how I snuck in the articulated hindlimb from the holotype. https://t.co/72vMa9sMy9
