Close your eyes and imagine the emptiness of North America thirteen thousand years ago. No cities, towns, highways, or planes. Not much of anything except a few bands of roaming Paleoindians spread across the expanse of an entire continent, living amongst countless herds of animals.

After its discovery in 1929 by Ridgely Whiteman in New Mexico, North American archaeology coronated the Clovis Paleoindian culture as royalty. Scientists proclaimed that the mammoth hunters who made the Clovis artifacts were the First Americans, i.e. the first humans to ever walk on North American soil. Since its discovery, Clovis technology has taken the breath away from artifact hunters and scientists alike. Books and magazine articles have filled our insatiable appetites for everything Clovis, including speculating about the lifestyles of those Paleoindians. No other prehistoric culture in North America has captured more attention than Clovis.

Clovis-type site in New Mexico.

We know from current archaeological evidence that Clovis flintknapping technology started showing up in North American sites around 13,500 years ago. But where did the Paleoindians who made that technology come from? That's the million-dollar question. The first and longest-held belief was the Clovis First Theory which in broad strokes stated that ancestral Clovis people originating in Siberia, crossed the Bering Strait from Siberia into Alaska during the last ice age when ocean levels were low. The theory proposed that the ancestral Clovis people holed up in Beringia until the Laurentide and Cordilleran ice sheets began melting and growing apart. The melting allowed the Clovis people access between the ice sheets to migrate south across Canada into the United States and Mexico. Since archaeologists contended that the Clovis people were the First Americans, they proposed that those people brought their flintknapping technology with them from Beringia, or they invented it once they arrived in the interior of  North America.  

The Clovis First Theory held water for decades and there are still a few scientists who hold onto that premise even though we have not seen any evidence, or smoking gun, proving that Clovis Paleoindians crossed the Bering Strait and brought their technology with them. In other words, if Clovis people and their technology came to North America through Siberia, why can't we trace Clovis technology back to Beringia or Siberia?

When I reference a smoking gun with Clovis technology, what exactly am I writing about? Clovis technology is represented in the archaeological record by stone projectile points, prismatic blades, blade cores, and unifacial tools made from blades. Clovis technology was heavy into blade technology. Clovis technology also included projectile points and foreshafts made from bone and ivory. Red ocher was also tied to the Clovis people. They covered the hematite-rich powder indiscriminately over artifacts and their burials. Unfortunately, other Paleoindian cultures besides Clovis dabbled in some of the above technologies and practices so we cannot attribute the technologies and practices exclusively to Clovis. The one technological innovation or smoking gun that distinguished Clovis from other Paleoindian cultures was a fluted projectile point! Clovis or Clovis-like projectile points are one of the most recognizable projectile point types in North America.  

Clovis projectile points are quite distinctive. They are one of a kind. Beyond their general outline and preferred biface reduction method, Clovis projectile points possessed a recognizable feature; Clovis flintknappers fluted most of their projectile points. The flutes or grooves started at the middle of the proximal end or base of the projectile point and terminated midway or less from the tip (see examples in figures one and four). Artifact hunters and scientists have discovered fluted Clovis or Clovis-like projectile points across the lower 48 states from coast to coast and from Canada to northern Mexico. That was an amazing dispersion of technology over a relatively short period of time. Some scientists estimate that the Clovis culture was only around for approximately three hundred years. Adaptation of Clovis technology by the populace must have been quick and decisive. But, where did the process for fluting originate, and by whom?

extraordinary flute. John Bradford Branney Collection. 

A master flintknapper named Bob Patten once wrote in his book Peoples of the Flute, "If, as it appears, the Clovis tradition [fluting] was invented here [North America], someone must have already been here to invent it."

An old saying stated that hindsight is 20-20, meaning that it is always easier to second guess the past than to forecast the future. To believe that there were no humans in North America prior to Clovis has always seemed naïve and unrealistic to me. Most other continents on the planets have evidence of humans dating back thousands and thousands of years before Clovis, even going back millions of years in Africa. Why would North America be the exception and remain human free right up until 13,500 years ago? What prevented humans from finding North America prior to Clovis? How did North America remain isolated while the cradle of humanity was happening all over the world? That makes no sense to me.

Ninety years after scientists first documented Clovis in New Mexico, there is now undeniable archaeological evidence that the Clovis people were not the First Americans. Sites with names such as Cooper's Ferry, Cactus Hill, Friedkin, Gault, Meadowcroft, and Topper have exposed the weakness in the Clovis First Theory. But why did it take so long? Perhaps, scientists were initially so locked onto the Clovis First Theory that egos got in the way and they poo-pooed anyone who disputed Clovis First. I have read that on some earlier archaeological sites digging stopped once Clovis was discovered because the investigators assumed there was nothing older than Clovis. 

In the past two decades, the Clovis First Theory has taken some hefty body shots and as far as I am concerned it is down for the eight count. The Clovis First Theory has been dead in my mind for some time. Archaeological discoveries older than Clovis are now aplenty, pushing human entrance into North America to 14,500, 15,000, 16,000 years ago, and beyond. It would not surprise me one bit if someday archaeological evidence discovers humans in North America as early as 25,000 years ago or maybe earlier. That just makes sense!

As far as the origin of Clovis technology, the mystery remains unsolved. In 2011, scientists excavated Clovis-like fluted projectile points at a site called Serpentine Hot Springs in northwestern Alaska (figure five). Could that be the smoking gun everyone was looking for?  Unfortunately, charcoal from that site dated to around 12,000 years, a thousand years younger than Clovis technology in the lower 48 states. If the people who made and used Clovis technology originated in Siberia and Beringia as the Clovis First Theory contended, and Serpentine Hot Springs was the smoking gun, wouldn't Serpentine Hot Springs fluted projectile points be older than Clovis fluted projectile points in the lower 48 states?  Serpentine Hot Springs indicates that perhaps Clovis technology migrated northward from the lower 48 states to Alaska, and not vice versa. 

The mystery remains as to the origins of Clovis technology.

Limaces, the Garden Slugs of the Artifact World

To get you in the mood for the world of Paleoindians, I am taking you on a brief trip back to 10,600 B.C. from the fourth book in my prehistoric adventure series titled CROW and the CAVE. In that particular scene, a young Folsom hunter called Cansha was attempting to keep a short-faced bear trapped in its winter den for a specific reason revealed in the book.  If the short-faced bear escaped, Cansha and his compadres would be in a world of hurt and would probably be on the menu for the beast's dinner! 

See you on the other side of the blue. Boy, I sure hope Cansha survives!      

“WHACK!”

A massive paw exploded out of the blackness of the cave. The paw’s curved claw ripped the tip of Cansha’s nose wide open. His eyes saw red as painful agony knocked him backwards. He fell to the ground onto a pile of broken bones and frozen beast feces. Cansha grabbed his severed nose with both hands and tried to stop the bleeding. The sensation from the pain was horrendous. Tears flooded his eyes. His hands filled with blood as he laid there in the muck. His nose stung with the fury of a rattlesnake bite.  Blood escaped through his fingers. The maneater shoved its front leg through the gap, its claws outstretched, searching for flesh. The boulder wobbled back and forth as the huge beast pressed its weight against it. Cansha writhed as he fought to escape the pain. He saw nothing through the blood and the tears. He stood up and staggered on unsteady legs. Cansha feared the beast would escape. A roar erupted from the cave. The boulder rocked further. The maneater’s leg squeezed out through the widening gap...

What?!?! What happened to Cansha?!?! Well, you don't expect me to give away the plot, do you? I am leaving you hanging with Cansha's life in the balance. You will have to read CROW and the CAVE to find out if the young lad survives, and if he did, how he did it.  

Now, it is time to get to the main topic of the article. I think you are going to like it...

Now that you experienced a very brief taste of what it was like in Paleoindian times, I now want to bring you up to speed on garden slugs. "Garden slugs?" you might ask, "I do not want to read an article on gardening!" Whoa! Don't leave yet! In France, the common 

Figure Two - an ordinary garden slug, 

or in France, a limace.  

garden slug is known as a limace. Most of us have experienced the bad fortune of spotting a limace or two on our lawns or gardens or crawling across the sidewalk (figure two). I have to admit that they are pretty nasty-looking creatures.   

So, what does that squirmy, ugly thing have in common with Paleoindians or archaeology? French archaeologists took the French word for a common garden slug, limace, and applied it to unifacial, humpbacked prehistoric stone tools that resembled the garden nuisance. Voila! Just like a sticky garden slug, the name limace stuck. 

Don't worry if you don't recognize the artifact type called limace. Most people don't. I didn't know about them until someone mentioned them to me and I then did some research. In my research on limaces, I noticed that people called them by other names like hump-backed scrapers, humpies, flakeshavers, awls, perforators, unifacial drills, slug-like scrapers, narrow side scrapers, unifacial flaked drills, groovers, slugs, bars, boats, Hendrix scrapers, bipointed bars, and I am probably missing a few. Whew! Since French archaeologists were the first ones to name that artifact type, I will call them limaces for this article. But if you see these other names in the literature, they are probably referring to limaces. 

Figure Three - Cross-sectional view of the limace from figure one. Note the plano-convex
or unifacial profile and retouch along the edges. John Bradford Branney Collection.

A limace is a type of blade that was flaked by a prehistoric knapper along both edges, forming what appears to be a slug-looking artifact (figures one and three). I am using Francois Bordes (1961) definition of a blade which he defined as a detached piece or flake of stone that is twice as long as it is wide. Limaces are plano-convex or unifacial in cross-section. A plano-convex artifact has a flat, mostly unworked underbelly (ventral side) and a humped back (dorsal side). Unifacial means a piece of knapped stone with flake scars on one face only. Limaces range in form from oblong to teardrop-shaped. 

Most investigators believe that prehistoric people utilized limaces as stone chisels for shaving and gouging hard materials such as bone, wood, ivory, and antler. A typical limace might have started out bi-pointed as in figure one but after hard use as a chisel, its working end most likely ended up beat up and blunted. Some limaces ended up with steeply angled faces due to unifacial resharpening much the same way as the "bit" or working end of a plano-convex end scraper. 

Based on their analyses, Grimes and Grimes (1986:40) stated that there was a high probability that prehistoric toolmakers hafted most limaces into the rigid socketed handles of bone or wood. That makes sense from a leverage perspective. The investigators cited evidence for hafting as edge rounding; deliberate abrasions, or grinding of basal edges; consistent lengths, widths, and thicknesses in their investigated sample; ‘trim to fit’ dimensions on the proximal ends; and lateral inflection points on some specimens. The investigators also believe that there were instances when they thought limaces were handheld.

Michael Sampson (2004) studied limaces found in the Tulare Lake Basin between Bakersfield and Fresno, California. In his paper, he proposed that true limaces, or “humpies” as he called them, were diagnostic artifacts of Paleoindians at least in the Tulare Lake Basin. He noted that investigators found humpie-like artifacts in both Siberia and Japan dating back to pre-Clovis times. Sampson also noted at least five other well-documented Paleoindian sites where investigators found limaces or humpies; the Shoop Site in eastern Pennsylvania, the Debert Site in Nova Scotia, the Bull Brook Site in Massachusetts, the Vail Site in Maine, and the Lehner Mammoth Kill Site in southern Arizona. Grimes and Grimes (1985) reported that investigators found small, elongated unifacially flaked tools resembling flakeshavers (what they called limaces) at several fluted point sites including Bull Brook, Debert, Plenge, Lindenmeier, Whipple, Shawnee-Minisink, and Krmpotich. Gramly (2000:37) reported that although limaces were a rare form, they were present in most large-sized Folsom, Clovis, and other fluted point Paleoindian assemblages.

Just like the shell-less garden slug, limaces don't get much respect. There does not seem to be much interest in limaces based on the lack of articles and research done on them. In my world, true limaces are a rare find and the destructive nature of their usage may be responsible for some of that rarity. It is difficult to find a limace in excellent condition like the ones in the figures. Those examples are still in good enough condition to be recognized as possible limaces. The difficulties lie with identifying limaces with damage and telling the difference between a limace and a scraper or blade tool. Not all limaces look the same or have the same dimensions or possess distinguishable or diagnostic characteristics like a Clovis or Folsom point. One person's limace can be another person's scraper or blade and vice versa.

There are assumptions we have to make about an artifact's past usage when we identify an artifact as a limace. When studying an artifact for the possibility of being a limace, I ask myself whether there is enough physical damage or wear on the proximal end of the artifact to determine its use as a chisel. I am sure that I have picked up many beat up, broken, or used up limaces that I did not recognize for what they were. I also have reasonable confidence that prehistoric people repurposed many broken and used-up limaces into other stone tools. Refurbishing worn-out, blunt-ended limace chisels into plano-convex end scrapers seem like it would be a worthwhile effort back in prehistoric times.
