Figure 6 in The ossified Meckel's cartilage and internal groove in Mesozoic mammaliaforms: implications to origin of the definitive mammalian middle ear
Figure 6. Phylogenetic relationships and distributions of main mammaliaform groups. Search options include: all characters unordered, equally weighted, accelerated transformation, multistate as uncertainty, rooting at tritylodontids, and monophyletic in-group. Numbers at each node represent assigned branch length, bootstrapping value, and Bremer supporting index. Bootstrapping value is obtained by 1000 replications of heuristic searches. Grey dots represent occurrences of genera (McKenna & Bell, 1997) used in the phylogenetic analyses. Grey bars are distributions of higher taxa (McKenna & Bell, 1997) represented by the genera. Character list, sources of data and detailed tree descriptions can be found in Wang et al. (2001).

Argillite Slant Groove Axe 36LAXXXX
One of three axes of similar form and material found in a 20' diameter after plowing in Lancaster County, PA near Susquehanna by Steve Nissly. Argillite is not available in the immediate area. These are large axes. This model represents the largest of the three at 330mm in length. The other two are 279mm and 273mm. Source: Objaverse 1.0 / Sketchfab

Grooved adz
This unusual artifact was found near Monroe, NC in 1973 by local landowner, Ken Batson. This suspected grooved adz is made out of local meta-argillite and has a deliberately modified area where a handle was likely attached. This distinct "neck" was created using a technique of pecking and grinding. Unlike a typical grooved axe, the bit end of this tool would have been oriented perpendicular to the handle and was not ground smooth. Note the edge damage on the bit end. An adz is woodworking tool used to dress, shape, or smooth timber and could have been used prehistorically to make wooden bowls, dugout canoes, or other wooden objects. It is unclear how old this object is, but if it was made during the time that many of the grooved axes were being made and used, it would likely date to the Late Archaic period (3000-1000 BC). It measures approximately 18.5 cm long, 5.2 cm tall, and 3.8 cm wide. This model was constructed by David Cranford using 46 digital photos and Agisoft Metashape software.
