I spent several enjoyable weeks in Montana last month, and shot some new video content there for my YouTube channel. Here are three videos that may be of interest to readers of this blog:

So many books have been written about dinosaurs, but this one looks at a deeper history of another important group: our own. Beasts Before Us is “the untold story of mammal origins and evolution.” The Cenozoic is often dubbed “the age of mammals,” but the story of our hairy, milk-guzzling brethren goes much deeper into geologic time. There have sort of been two ages of “mammals,” author paleontologist Elsa Panciroli …

Callan documents a geological stroll along the coast of Esterillos Oeste, in central southern Costa Rica, investigating the sequence of sediment in the Punta Judas Formation (Mid-Miocene) exposed there. Fossils, sedimentary structure, diagenetic features, structural deformation, and modern weathering all make prominent appearances.

Five books get the Callan mini-review treatment: two novels from Amor Towles, an account of life in prison under solitary confinement, a history of Virginia slavery during the War of 1812, and finally a family account of the discovery of the fossil Hesperornis, a toothed bird, and various associated tangents.

Here’s a cool little book about the paleobiology, ecology, and behavior of cephalopods: Squid Empire. The author, Danna Staaf, has a PhD in marine biology and –more importantly– a lifelong fascination with squid, octopuses, cuttlefish, and nautiloids. This work is a history of the cephalopod clade – going back into deep time, before the Cambrian Explosion, dwelling on ancestral forms and luxuriating in the ammonites (now sadly extinct — or …

A book by Nick Pyenson (of the Smithsonian Institution’s National Museum of Natural History) details the past, present, and future of whales. Combining paleontology, oceanography, environmental awareness, evolution, and history with personal stories of field work and insight, it’s a compelling tale of modern science on charismatic, mysterious creatures.

A virtual field trip to examine some deepwater clastic sediments shed off the first phase of Appalachian mountain building, and deformed in the third phase. It’s a lovely day for a field trip to the late Ordovician!

When Bugs Were Big, Plants Were Strange, and Tetrapods Stalked the Earth: A Cartoon Prehistory of Life Before Dinosaurs, by Hannah Bonner
It has been a while since I’ve reviewed any kids’ books here, but this one was so good that I just have to tell you about it. My son is now 6 and a half years old, and he’s interested in all sorts of natural history topics. Given that I’m a geologist, he’s probably more Earth-science-focused than the average kid, but my wife is a biologist, so he’s got plenty …
