Helen James, the Curator-in-Charge of the bird collection at the National Museum of Natural History, is here to today to take our questions! Ask her whatever you want about extinct birds, bird evolution, and the secrets contained in the fossil record.
Dunkleosteus hunting ammonites by Chris Tomlin
By Mark Witton:
"Male and female (respectively) Jurassic ammonites, Erymnoceras coronatum. The size difference between these genders is well constrained by fossil data, but the appearance of the actual animals is not.” Keep reading: Palaeoartworks, the case studies, part 3: Ammonites and… extinct snails?

Thank you!, here’s my ammonite tag, but I’ll try to add more illustrations.

Vi los titulares hace poco pero estoy desinformadísimo, lo que está claro es que llegaron volando, (habilidad que todos los delfines tienen, como sabe cualquier poseedor de la guía del autoestopista galáctico). A las pruebas me remito:

The New Spinosaurus
by Brian Switek
Spinosaurus has changed dramatically since I was a kid. The model I used to terrorize my other toys with looked like an overgrown Allosaurus with a giant sail on its back.
As paleontologists rearranged the dinosaur family tree and found new species, however, they realized that Spinosaurus was a very different sort of animal, allied with croc-snouted, heavy-clawed dinosaurs like Baryonyx. When Spinosaurus finally tore up the celluloid in 2001′s Jurassic Park III, it was as a monstrous carnivore with giant claws, an elongated snout filled with conical teeth, and a flashy fin atop its back. And the evolution of Spinosaurus imagery has not stopped.
A paper out in Sciencexpress today proposes that Spinosaurus was far stranger than paleontologists expected.
The core of the new study, led by University of Chicago paleontologist Nizar Ibrahim, is a partial skeleton of Spinosaurus found in the 97 million year old rock of Morocco. The importance of the new specimen is in revealing parts of Spinosaurus never seen before. The skeleton includes parts of the skull and some vertebrae, but the real keys to the new Spinosaurus are the hips and hindlimbs…

Wading by Luke Mancini:
"Inspired by egrets in the creek between my place and work, a non-avian cousin enjoys foraging in a somewhat more natural environment. I had the tail in a more traditionally ‘dinosaur’y curve for most of the process but actually quite like the straight (more accurate) version in the end."
