- Descriptions of rock formations where trilobites are found.
- Excavation and restoration of trilobites.
Trilobites are a well-known fossil group, possibly second most famous only to dinosaurs. With their easily fossilized exoskeleton, they left an extensive and diverse fossil record. They began a drawn-out decline to extinction during Late Devonian time, when all but one of the trilobite orders died out.
This meticulously researched reference guide is a photographic atlas and descriptive compendium on the trilobites of Coal County, Oklahoma. The species described lived during the Lower Devonian in a shallow tropical ocean that had advanced over the landscape of North America. More than twenty species are exquisitely preserved in Oklahoma's limestone rocks.
Each species is carefully illustrated, including thorough descriptions, so that those familiar and unfamiliar can understand and appreciate these amazing creatures. The most current scientific research on these trilobites is also included. For those wishing to pursue a deeper interest in trilobites, a comprehensive bibliography lists hundreds of sources of information for further study.

Exactly what I wanted
This robo-vac works great! Most of the well known products in this category are full of crap that you don't need, or is even spying on you. I'm sorry, but my appliances don't need WIFI, camera's, mapping features and an internet connection to send them to... who??? This unit has everything you need and nothing you don't. I bought it because my dog is shedding like crazy and leaving my floor looking like it needs a haircut. The Eufy has done a great job of picking up ALL of the dog hair, dirt and small particles, and has yet to become clogged. The floor it is cleaning is a linoleum floor that has a low pile rug and it cleans both very well. The Eufy runs for well over an hour and one of the best things about it.... it is VERY quiet. Emptying the dust bin is super easy, and cleaning the filters is very easy as well. The Eufy comes with extra side brushes and an extra roller. I have not had to change any of them yet, but maintenance and cleaning of these items has been made very easy as well. It comes with a well thought out cleaning tool that makes cleaning easy. It has a cutter on it, similar to an envelope opener, that gets under hair that wraps around the roller and and slices it off. This is a problem with ANY vacuum that has a roller, and this tool works very well for this. To be honest, I wasn't sure what to expect at the price point, but the Eufy works better than the older I-robot I had some time ago and is far easier to maintain. The very first time it ran it was learning the room and did not make it back to the dock, but every use since, it has always gotten back and docked. If you want a robot vac that you can start with a remote or program a schedule in, without WIFI, camera's, and yet another app to install on your phone, I highly recommend the Eufy... you won't be disappointed.

The Silent, Obsessive Predator in the War on Filth: A Dispatch on the eufy L60
Size: eufy L60 SES (renewed)
Dateline: My Living Room Floor, a Battlefield of Invisible Grime, 1:30 AM. The house is quiet. The world is asleep. But in the darkness, a hunter stirs. It detaches itself from its charging dock with a soft, electronic whir, its single laser-eye pulsing with a cool, blue light. This is not a vacuum cleaner. This is the eufy L60, an autonomous, dirt-seeking assassin, and it is beginning its nightly patrol.
To call what this machine does "mapping" is a gross understatement. This is military-grade reconnaissance. On its maiden voyage, the L60 didn't just bumble around bumping into things. No, it conducted a systematic, laser-guided survey of my entire living space, rendering a perfect, eerily accurate floor plan on my phone. It knows the terrain. It has identified the chair legs, the table supports, the treacherous geography of the area rug. It has logged the coordinates of every obstacle. It is operating with a level of tactical awareness that would make a special forces operative blush.
And then, the hunt begins. With 5,000 Pascals of raw, unadulterated suction power, it doesn't just "pick up" dirt; it inhales it. It moves in straight, deliberate, overlapping lines, a methodical grid search that leaves no square inch un-scoured. Dust, crumbs, the detritus of a life lived with a certain amount of reckless abandon—all of it vanishes into its maw. And hair… good heavens, the hair. It attacks strands of human and pet hair with a special kind of ferocity, its "Hair Detangling Technology" acting like a tiny, internal machete, chopping the stuff up before it can choke the machinery. It is a savage and beautiful solution to an ancient and vexing problem.
But the true genius, the feature that elevates this from a clever gadget to a genuine domestic revolution, is the self-empty station. This monolith is not just a charger; it is the L60's base of operations. After its patrol is complete, the little predator dutifully returns to the dock. And then you hear it—a ferocious, ten-second roar, like a miniature jet engine firing up. That is the sound of every speck of filth the robot has collected being violently sucked from its belly into a sealed bag within the tower.
The result? You don't have to do a thing. For up to 60 days, this silent partnership continues. The robot hunts, it cleans, it reports back to its base, it unloads its grim bounty, and it prepares for the next mission. You are completely removed from the dirtiest part of the process.
This eufy L60 is not just an appliance; it's a quantum leap. It is a quiet, frighteningly intelligent, and ruthlessly efficient solution to the endless, soul-crushing war against domestic filth. It maps its battlefield with perfect precision, it hunts its prey with relentless power, and it handles its own dirty work. It is, without a doubt, the single greatest ally you could ever have in the quest for a clean floor. Absolutely amazing.

Waste of money
Size: eufy L60 SES (renewed)
This vacuum is a total let down. It cleans well enough however it has lost its network connection every month since I have owned it. Not only do I have to take 20 minutes to get it to finally reconnect, but it also wipes out the map that is stored. So I can’t clean until it re-maps the floor, I have to re-divide the rooms, and ultimately can’t clean for close to 2 hours when I need it most. Don’t waste your time with this unit unless you want to deal with network issues every month

Great Price, Great Quality, Save your money from other over priced Brands
I absolutely love this! Just as good as any of the more expensive brands! It has great cleaning abilities and is able to get in every corner and crevice. This quality is amazing and it has a mapping feature with a remote to set it up. Powerful suction, connects to the wifi easily and has a perfect spin rate so it doesn't miss a thing! My biggest issue is that I wasn't using it as much as I should! Make sure you set up a timer and it will take care of the rest!
