Icnita Dinosaurio Terópodo “Gigante” (by Paleoymas)

Huella fósil de 69 cm de longitud.

The hard drought in Texas this summer has taken its toll; crops are shriveled, rivers are drying up and even cacti are showing stress. But droughts such as this offer a rare glimpse of an extensive collection of dinosaur tracks at the Dinosaur Valley State Park near Glen Rose, Texas. Normally covered in water, the tracks of sauropods and theropods are for the time being exposed in the limestone bed of the Paluxy River. This small sauropod print is approximately 12 in (30 cm) across. The setting for this park was formed by sediment deposited more than 100 million years ago along rivers that once flowed into an ancient sea. Over perhaps the last 1 million years, the layered sediment has been gradually worn away revealing the long ago submerged footprints. Photo taken on August 2, 2011.

Aldrovandi describes this specimen as a “Rock pregnant with a shell”. b. Aldrovandi describes such fossils as “Astroitis”, referring to the star-like morphology of certain echinoderms and corals. (via Storia della Geologia)

I love this stuff. I love a rock that is, basically, all shells and can make cannonballs bounce. So when I had a chance to get my hands on some coquina for the first time ever, you can bet I fondled it. It’s harder than you’d expect for something famously soft enough to absorb enormous balls of metal hurtling toward them at speeds meant to destroy. It feels quite solid. And very, very shelly.

Fossilized ripples! Well, at least I believe they are, via my one college geology course.

Mesosaurus brasiliensis should gladden the hearts of all geologists. This is a Permian freshwater critter, a marine reptile that nommed on fish and swam around in lakes and rivers in what became South America and South Africa. It couldn’t cross oceans, and there were no such things as bilges back in the Permian in which stowaways might travel. Turns out this aquatic reptile is excellent evidence that South America and South Africa were once joined - score one for plate tectonics! (via En Tequila Es Verdad)

Project Photofly can be used to create 3D models from 2D digital photographs - such as this fossil of an ancient warrior pig. Colleagues from across the globe can then take measurements from the model without having to physically handle the fossil.

Amazing free, easy to use software.
