I found a key to figure out a species of Solenochilus, and I would like to attempt to create a visual guide of the differences in the key. Usually it's a A/B situation. While it's clearly written, I'm still having some trouble figuring out what the difference is. So to start: Suture with ventral saddle. Suture with ventral lobe. I've found this, but it seems like this type of suture has both: Solenochilus has an exposed siphuncle, so the middle (venter) suture is usually interrupted by this. It's also usually straight. I have another 11-14 measurements aside from this first one. Help Update: This is the entire guide for those curious: https://docs.google.com/document/d/1hvqE3_MH0ke0XKCPgL2YeOaddCsIEOU5uOQyZxypCqU/edit?usp=sharing

When trying to classify fossils where the species is unknown which do you use? For example is it Tyrannosaurus sp. or Tyrannosauridae indet.? Edit: Using Albertosaurus as an example, I now believe it is something like this. Since Albertosaurus is hard to differentiate from Daspletosaurus and Gorgosaurus any finds should be labelled 'Tyrannosauridae indet.', but if you could identify it as Albertosaurus and didn't know the species (sarcophagus etc.) it should be labelled 'Albertosaurus sp.' until the species is known.
