3. Clovis is in New Mexico, not Texas.
^^^^'Clovis' (the city) is indeed in New Mexio, but what they were referring to was the Clovis Period of Paleo Indians and the Clovis lanceolate points associated with that group and time period.
The name for that point type does come from first discoveries in Clovis, New Mexico but is not what was being discussed in the video.
The Clovis 'point' is the most widely distributed projectile point in North America.
