The first one is Lepidophloios. Wider than tall leaf scars.

 

 

Perhaps, but there are also Lepidodendron species that have leaf scars that are wider than long.

 

"Lepidodendron is one of several fossil genera of arborescent lycophyte stems characterized by persistent swollen leaf bases (leaf cushions) from which the more distal leaf laminae have usually been shed. The species are distinguished on the overall shape of their cushions, which may be almost isodiametric to several times longer than broad, diamond‐shaped leaf scars that may be isodiametric or broader than long, surface markings on the cushions, the position of the ligule pit aperture and the presence or absence of external parichnos."
