The Antilife Shell spell states:
An affected creature can cast spells or make attacks with ranged or reach weapons through the barrier.
This suggests that a human could attack with a glaive, since the weapon can reach the full 10 feet through the shell and strike the caster.
Does this include monsters whose natural weapons have a reach of 10 feet or greater? For example, a dragon's tail attack which has a 15-foot reach or a T-Rex's bite which has a 10-foot reach.
