Tomorrow on See Jurassic Right, we continue our Jurassic Park III twenty-fifth anniversary celebration with paleontologist/science communicator, @cambriancam.bsky.social! It’s Summer Flicks With Scientists. Subscribe and stay tuned.

About 20 years after Benjamin Waterhouse Hawkins made the original Hadrosaurus mount for the Academy of Natural Sciences, three* plaster casts were produced for other museums: The US National Museum, the Field Columbian Museum, and the Princeton Museum of Geology.

It's 96 degree weather here in Mississippi collecting fossils from the Late Cretaceous (Late Campanian) Demopolis Formation. ~76 million years ago, the black belt region of Mississippi and Alabama was covered in a warm shallow sea teeming with life. The round objects you see around me are oysters!

There are oysters everywhere! The most common oyter at this locality is the classic Exogyra. These were large oysters that dominated the black belt region here in Mississippi and Alabama.

Continuing #FossilFriday with another critter that biomineralized a #calcite exoskeleton (vote! It's too close!) ... here we have a couple spiriferid brachiopods. 🧪⚒️

Dive into Alabama's prehistoric past! Join the Alabama Museum of Natural History for our annual "Alabama Fossil Fest" on Saturday, September 12, 2026, from 1:00 - 4:00 P.M. at Smith Hall on The University of Alabama campus. Full details at the link below. almnh.museums.ua.edu/alabama-foss...

I'll be attending the Alabama Fossil Fest located at the Alabama Museum of Natural History. I'll have a table set up highlighting the rich paleontological history of the southeastern US.

This #FossilFriday I wanted to share a teaser for some work coming out this week on how best to go about retrodeforming our #Ediacaran fossils here in Newfoundland. These are from another new fossil site with a lot of tectonic compression that changes the appearance of the fossils needing retrodef.

Devonian Seastar FTW!

Welcome back to #mineralmonday and Happy Labor Day! Here are beautiful crystals of the calcium rich Grossular Garnet species known as Hessonite. This specimen comes from Tungsten Hills in Inyo County, California. Can you see why Garnet is my favorite mineral group? I mean just look at this sample!

Gorgeous Pacific mastodon (Mammut pacificus) molar found in a stream during red legged frog habitat restoration in the Santa Cruz Mountains in the Mid-Peninsula Open Space preserve! Another lovely Pleistocene mastodon specimen from the bay area. Read about it here: tinyurl.com/bd5axunn

If you can spare a few bucks, some colleagues are trying to bring some paleobiology to the public in St. Louis!

Microcrystalline quartz forms in concentric bands as silica-rich fluid fills a void — each layer records a different mineral concentration. Cutting reveals what took millions of years to build. 💎

Behold this cephalic spine from a Cretaceous age hybodont shark! 😈🦈 This specimen was recently discovered by a UA student during a museum-led fossil hunt in Greene County, AL. Two pairs of these striking spines adorned the heads of male hybodont sharks. #FossilFriday #RollTide

Welcome back to another #FossilFriday Here is a complete specimen of the extinct ark clam Anadara aequalitas from the late Pliocene Tamiami Formation (Pinecrest Beds) that I collected in Manatee County, Florida.

Welcome back to #MineralMonday Here is a beautiful piece of purple Botryoidal Chalcedony (sometimes informally called "Grape Agate") from Indonesia.

Welcome back to #TrilobiteTuesday Here is a massive pygidium from an undescribed Scutellid trilobite from the Lower Devonian rocks of Morocco. This would have been a monster trilobite if it was complete. The tail alone is about 3 inches across!

Welcome back to #mineralmonday Here is a large well formed Orthoclase Feldspar from Shigar Valley in Gilgit-Baltistan, Pakistan. These crystals are found in silica-rich Pegmatitic Granites in the region. This is by far the best Feldspar specimen in my collection. Textbook example I would say!

Welcome back to another #FossilFriday Here is an undetermined arthropod trackway (Cruziana?) from the Middle Mississippian (Lower Carboniferous) Lodgepole Formation from the Little Belt Mountains in Montana.

Welcome back to #TrilobiteTuesday Here is a beautifully enrolled Paciphacops campbelli from the Lower Devonian (Lochkovian) Bois D' Arc Formation in Bromide, Oklahoma.

I love ammonites. This one is absolutely massive, and the shell pattern is even better up close. #Fossils #Paleontology #Ammonite

Oh yeah, I live right down the road where they filmed Stranger Things season 3. It was called Starcourt Mall in the show. Actually a lot of this show was filmed right here in the state of Georgia.

Welcome back to #FossilFriday Here is a beautiful example of a cross section of a Stromatolite (Cryptozoon?) from the Lower Ordovician (Tremadocian-Floian) Gasconade Dolostone collected by the late Dr. Bruce Stinchcomb in Sullivan, Missouri.

A beautifully preserved fossil fish at the Denver Museum of Nature & Science. The museum has an excellent collection that goes well beyond dinosaurs. #Paleontology #Fossils #Denver #Fish #Museum

This fossil is an example of what is called a "mortality plate" as it contains the remains of several animals that all died around the same time. Trilobites were some of the first animals to evolve an exoskeleton, and as a result fossilize very well compared to other Cambrian creatures.

Hunt was a success and the family were very pleased with their finds. I came home with two nice chucks of reptile bone. Pics to follow.

Up for another #fossil hunting tour near #Whitby. Who knows what wonders we'll find? Last time we found a piece of reptile (?) Bone with crinoids attached, and lovely plant fossils. If you want a tour then send me a DM. But be quick, August is filling up fast.

Welcome back to #fossilfriday #sharkweek Here is a tooth from the shark Deltoptychinus. Deltoptychinus belongs to the group of Cartilaginous fish known as the Holocephalians. This specimen comes from the Upper Mississippian (Lower Carboniferous) Indian Springs Shale in Crawford County, Indiana.

We are back on our #sharkweek posts! Here are two teeth from the extinct Lamniforme shark Squalicorax kaupi. I collected these two specimens back in 2019 from the Late Cretaceous (Late Campanian) Demopolis Formation in Belden, Mississippi.
