Getting to Richards Spur: Directions and Access Points
Tucked into the red earth of Comanche County, Richards Spur sits at coordinates 34.760069°N, -98.3869985°W—a pinpoint on the map that belies its outsized reputation among paleontologists and fossil hunters. You’ll find this legendary fossil site north of Lawton, adjacent to Fort Sill military base, at roughly 1,178 feet elevation. The catch? It’s embedded within Dolese Brothers’ active limestone quarry, meaning you can’t simply roll up unannounced.
From Oklahoma City, take I-44 south toward Lawton, then navigate north via state highways and farm-to-market roads. Before making the trek, contact Dolese’s general office at 20 N.W. 13th regarding entry permit details—quarry company operations take precedence here. Without clearance, you’re facing locked gates and liability issues. This isn’t public land; respect the boundaries.
What Makes This Semi-Abandoned Mining Town Special
You’ll find yourself standing at the intersection of industrial grit and paleontological treasure, where active limestone quarry operations continue alongside some of North America’s most significant fossil beds.
The reddish cave fill exposed in these Permian-age deposits has yielded pristine specimens of 289-million-year-old amphibians, reptiles, and early synapsids—creatures preserved in extraordinary three-dimensional detail.
This working quarry’s remote location in the Arbuckle Mountains means you’re witnessing both Oklahoma’s mining heritage and a site that’s rewritten textbooks on early terrestrial vertebrate evolution.
World-Class Fossil Discoveries
The crumbling limestone hills around Richards Spur harbor one of paleontology’s most extraordinary treasure troves—a 288-million-year-old cave system that’s rewriting the story of early land animals. You’ll discover where paleontologists unearthed the world’s oldest fossilized skin—a fragment from *Captorhinus aguti* that’s 21 million years older than any previously known specimen.
The exquisite fossil preservation conditions here stem from a rare convergence: oxygen-starved caves, fine clay sediments, and petroleum seepage from ancient marine deposits. This chemical cocktail perfectly mummified soft tissues that normally vanish within days. Since systematic excavations began in 1932, researchers have repeatedly returned to collect three-dimensional skin fragments with crocodile-like pebbled surfaces.
These discoveries illuminate ancient land animal evolution, revealing when reptiles, birds, and mammals developed their tough, scaly armor for terrestrial life.
Active Quarry Operations
Unlike most ghost towns frozen in time, Richards Spur pulses with industrial life around the clock—massive crushers grinding limestone while paleontologists race against bulldozers to salvage 289-million-year-old treasures.
Operational logistics reveal a remarkable dual existence:
- Round-the-clock extraction: Six-day weeks with two production shifts plus maintenance, consuming massive electricity that forces evening operations to avoid overloading Oklahoma’s power grid
- Industrial scale: Specialized Irish machinery produces 12-36 inch riprap across thousands of feet of conveyor belts spanning one square mile
- Calculated destruction: Blasting exposes new fossil-bearing cave networks continuously, though Permian sediments get discarded without documentation
The environmental impact extends beyond alkaline reservoirs (pH 8-8.5) and power consumption. You’re witnessing systematic erasure of irreplaceable geological records—vertically-tilted Ordovician limestone harboring karst caves filled with ancient bones, demolished before detailed mapping occurs.
Remote Limestone Mining Heritage
Since 1907, Dolese Brothers’ limestone quarry has clawed through more than a square mile of Arbuckle Mountain bedrock—a pre-statehood operation that predates Oklahoma itself by mere months. You’ll witness quarry history still unfolding: conveyor belts rumble six days weekly across 24-hour shifts, extracting Ordovician limestone for construction adhesion.
The mining footprint tells its own story—half the site remains untouched after 113 years, waiting beneath your feet. This isn’t preserved amber; it’s living industrial archaeology where blast schedules dictate access and ancient cave systems appear overnight in fresh-cut walls.
Workers first reported strange fossils here in 1932, but the hammers never stopped. You’re exploring a location where commerce and paleontology collide, where million-year-old secrets emerge between dynamite charges and crushing equipment.
The Ancient Limestone Quarry That Changed Paleontology
North of Lawton, where massive limestone blocks emerge from industrial crushers, the Dolese Brothers Limestone Quarry conceals one of paleontology’s most revolutionary sites. Since quarry workers first reported fossils in 1932, this unassuming industrial operation has yielded discoveries that’ve rewritten evolutionary history.
Where limestone crushers meet ancient history, an Oklahoma quarry has quietly upended our understanding of early reptilian evolution.
What makes Richards Spur extraordinary:
- 289-million-year-old reptile skin—the oldest ever found, preserved in oxygen-poor cave sediments
- Petroleum seeps that mummified soft tissues before decay could erase them
- Articulated skeletons of captorhinids like the 10-inch Captorhinus aguti, revealing pebbled crocodile-like epidermis
You’ll find academic studies still examining how ancient oil and fine clay combined to capture details usually lost to time. The evolutionary implications stretch from these early amniotes to modern bird feathers and mammalian hair follicles—all documented where limestone meets paleontological gold.
Exploring the Cave System and Fossil Discovery Sites
Deep beneath the working quarry, where Ordovician limestone tilted skyward 300 million years ago, an ancient karst system cradles paleontology’s most intimate secrets. You’ll discover a rich cave environment where oxygen-starved sediments and oil seeps from the Woodford Shale created unique preservation conditions unlike anywhere else on Earth.
Picture stalagmites and stalactites encasing 289-million-year-old creatures in calcite tombs, their skin mummified by petroleum before decay could claim them.
The Mays’ collection site reveals fossil treasures embedded in soft claystone and calcite conglomerates. Here, tar-blackened bones of Captorhinus aguti rest alongside fearsome Dimetrodon remains. These fissure fills, packed with ancient clay and mudstone, transformed the caves into time capsules where pioneering reptiles, synapsids, and amphibians met their final fate.
Best Times to Visit and What to Expect at an Active Quarry
You’ll want to plan your Richards Spur visit carefully, as this isn’t a passive museum experience but an active industrial site where massive crushers grind limestone and haul trucks rumble past exposed fossil layers around the clock.
