I mean it doesn't really point to another group that did use projectile points that lived and vanished before the Clovis people showed up.
That is exactly what they are saying that it does point to. Artifacts including spear points that are not of Clovis design found in a layer beneath Clovis artifacts.
The clovis people left points. They were thought to be the first to use spear points. This apparently earlier people also used spear points. Both Clovis points and these earlier points have been found at the same site with the Clovis points overlaying the earlier ones.
There is an ongoing (as in more than 35 years now) debate about the timing of the first modern humans on the American continent.
Some very credible people argue that the Bering Land Bridge is the path and that framing the period of the bridge's existence also defines the first appearance of humans in North America. Their (current) estimates are that glacial ice was moving too fast for any reasonable migration until the closing period of the Last Glacial Maximum (which ended about 13,000 years ago. Based on that standard, the Land Bridge proponents suggest a small warming 2,000 to 4,000 years before the end of the Last Max would have stabilized the Ice across the Bering Sea roughly along the arc of the current Aleutian Island chain, and allowed a walking migration. Global warming (caused by Eskimos driving neolithic Land Rovers) ended the intermittent Bering Land Bridge before 10,000 years ago. That would put the first humans on North America less than 16,000 years ago and means that they came to America as experienced knappers with some very modern tools.
But there are other theories that have some credibility. Interestingly, the University of Texas (40 miles from the dig site) supports the "walking across the Bering" theory - but Texas A&M (the sponsor of the reported dig) opts for an older date. One theory is that humans crossed portions of the North Pacific by boat AND crossed from North Africa/Europe by boat - much earlier. This concept could put humans on a very frozen North America as early as 22,000 years ago (20,000BCE). This theory also has the two cultures meeting very, very soon (within 1 or 2,000 years) after they reached America.
The early arrival theory means a stone using culture, arriving by boat, that likely learned to knap flint on this continent instead of bringing that knowledge with them. That idea would also explain some of the very primitive, but very present, spear points and arrow (atlatl) heads that were very different on both coasts, but seemingly at the same time, were refined into very similar points. The supporting evidence for early arrival also includes the preserved remains of hollowed logs large enough for offshore use, hammered stone points likely used for marine hunting, a preponderance of older "village" sites below the "max" glacier line, with the majority of sites north of the maximum glaciation being newer.
The fun part of these studies is that if UT is right then A&M just found what may be the oldest ever spearpoint - - - But if A&M is right, then UT is still in the running to prove themselved wrong.
One looked suspiciously Clovis to me also, but the more crude ones don't look Clovis and the Tx A&M guys seem to think they are not. I don't know just passing along stuff on the InterWebs.
A good place to live is a good place to live. Multiple occupancy on a site is the rule, not the exception. Most of the sites that have been excavated in NC have artifacts from historic tribes all the way back to early Archaic times or even back to the late Paleo period. And we are now living on most of those sites ourselves.I wonder if it was the same people and scientist just haven't known that they used projectile points?

Especially when they find older artifacts at the same sites as the Clovis or others. I do realize that this does sometime happen.
The Etowah Indian Mounds is an example. Built by people of the Mississippian culture, used later by the more modern Cherokee.

There are a lot of multi-occupational sites around here that cover all the time periods from the Early Paleo all the way up to pre-Columbian sites. Points and tools from all these time periods have been found on them. I was lucky enough to be able to hunt on one of them for several years.
I wonder what the next group thought when they found an artifact of a previous
group?
