We report details of a unique association of hadrosaur and therizinosaur tracks found in the Late Cretaceous lower Cantwell Formation, Denali National Park, central Alaska Range, Alaska.
This rock unit is now well-documented as a source of thousands of fossil footprints of vertebrates such as fishes, pterosaurs, and avialan and non-avialan dinosaurs.
The lower Cantwell Formation in this area consists of numerous fining-upward successions of conglomerates and pebbly sandstones, cross-stratified and massive sandstones, interbedded sandstones and siltstones, organic-rich siltstones and shales, and rare, thin, bentonites, typically bounded by thin coal seams, and it contains a diverse fossil flora.
We report the first North American co-occurrence of tracks attributable to hadrosaurs and therizinosaurs in the lower Cantwell Formation.
Although previously un-reported in North America, this association of hadrosaur and therizinosaur tracks is more characteristic of the correlative Nemegt Formation in central Asia, perhaps suggesting that parameters defining the continental ecosystem of central Asia were also present in this part of Alaska during the Latest Cretaceous. ...”

“A superhighway? I invented that!” - Al Gore
Reminds me of the 1960-70s game "Twister"...
Alaska Ping.
And no doubt they were cruising in the left lane at 10 MPH below the posted speed limit, with their right turn signals blinking nonstop...
“Build the wall!” the therizinosaurs trilled, “Build the dang wall!” But they had no opposable thumbs and so could not build the wall. And just where are they now? Extinct, that’s where.
drill baby drill, dinosaurs make good oil.
To my knowledge, no Therizinosaur skull has ever been found. Just arms, claws, and leg bones.
How can anybody tell it was a plant-eater?
They must be putting feathers on dino’s again to justify “evolution”.
