Establishing a extensive dinosaur excavation site in the basal ferrugenous paleosol level just above the J-K boundary was the prime goal for weekend, Next establish if a correlation of the new BYU ankylosaur bonebed with the Gastonia lorriemcwhinneyae bonebed. Stay tuned....

SCORE!!!! #FossilFriday Today; checking out the basal Cedar Mt ferrugenous paleosol, Berriasian. Josh Lively walked up on a bunch of bones weathering out. Nice polacanthine 2nd cervical spine, iguanodont jaw & ungual. Enough material to name polacanthine n. Sp. C. @utahpaleo-ufop.bsky.social

That would probably be an eolian sandstone bed in the lower or middle Jurassic, the Smith Cabin is nestled in the middle Jurassic Carmel Fm.

We are talking about conducting a paleo inventory of unexplored regions of the Blanding Basin in the spring for which we will be recruiting volunteers. A number of us are retiring in next few years. These positions will be highly competitive. @utahpaleo-ufop.bsky.social @jeremybroberts.bsky.social
