Lizard lizard on the wall

 Cretaceous; BR,MG,
When you think about fossils, lizards might be not be one of the first groups that springs to mind. However, they do have a pretty neat fossil record, stretching back over 150 million years. One group of lizards, iguanians, are still around today and comprises about 1700 different species! One sub-group of these iguanians, acrodonts, are thought to have originated in east Gondwana – part of the ‘old world’ including Africa. Acrodonts are named after weird features in their [...]

Huw S. Groucutt and colleagues in Evolutionary Anthropology lay out the evolving story of the dispersal of Homo sapiens from Africa. The review brings together fossil, genetic  and archaeological data which now strongly leans towards a scenario of multiple migrations of Homo sapiens out of Africa beginning more  than hundred thousand years ago. These migrations followed ecological  windows

This picture shows the cast of a Sarcosuchus imperator crocodyliform aka SuperCroc. This distant relative of the crocodile lived during the Creteaceous Period. Their fossils are found in South America and Africa. The cast is based off a fossil found sub-Saharan Niger Africa by University of Chicago paleontologist Paul Sereno. Fossil cast was on display at Children's Museum of

Great opening ceremony at EAGE 2915 at the Madrid IFEMA convention center. Beautifully managed by President Phillip Ringrose with award citations read by President-Elect Mohammed Al-Faraj (my friend from CSM and Aramco days). Had a nice chat with Gerry Schuster of KAUST about many things, including interesting work he is doing with hominid researchers in Africa. Maybe I'll tag along sometime to see if I can help. Also enjoyed hearing about his small scale field experiments on noise, [...]

Vi segnalo che dal 6 giugno al 10 gennaio prossimi, Milano ospiterà la Mostra su Spinosaurus che nei mesi precedenti era ospitata a Washington (USA). Si tratta di una collaborazione internazionale tra il Museo di Milano, l'Università di Chicago, la Geomodel e la National Geographic Society. Per motivi che spiegherò prossimamente, io visiterò la mostra in autunno.

But there are certainly a great many places I have never visited, and may never have the chance to. I am also lucky to have a cadre of former

Saharan dust feeds Amazon rainforest just enough to replace lost nutrient 

AGU Meetings [2015-02-24 16:02:51]  recommend  recommend this post  (40 visits) info
The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rainforest is a dense green mass of humid jungle that covers northeast South America. But after strong winds sweep across the Sahara, a tan cloud rises in the air, stretches between the continents, and ties together the desert and the jungle. It’s dust. And lots of it. Scientists have not only used a satellite to measure the volume of dust that makes this trans-Atlantic [...]

Human Evolution- Multiple Opportunities For Migrating "Out Of Africa"

There really seems to be a connection between orbital mechanics and human behavior, though not in a way astrologers think it to be! From the early online February issue of Geology- The dispersal of human populations out of Africa into Arabia was most likely linked to episodes of climatic amelioration, when increased monsoon rainfall led to the activation of drainage systems,

Il “paradosso” di Spinosaurus sensu Ibrahim et al. (2014) deriva fondamentalmente da un singolo fatto: il rapporto tra la lunghezza delle vertebre dorsali e la lunghezza degli elementi del cinto pelvico e dell'arto posteriore. Per chiarire questa frase, ho plottato le misure pubblicate da Ibrahim et al. (2014, informazioni supplementari) relative all'ileo, femore, tibia rispetto ai medesimi

La “tesi quadrupede” su Spinosaurus da parte di Ibrahim et al. (2014) è stata sicuramente la parte più controversa della pubblicazione più controversa in theropodologia nello scorso anno. Mentre uno stuolo di critici ha attaccato l'ipotesi di partenza di quello studio, ovvero l'esistenza effettiva di uno spinosauride con quelle particolari proporzioni scheletriche, io ho accettato la

All warmed up and nowhere to go: The missing El Niño of 2014

 US,PE,
In 1997, a record-breaking El Niño event in the Pacific Ocean brought rain to California, flooding to Peru, and drought to Africa. Earlier this year scientists said that warm currents in the Pacific Ocean presaged the biggest El Niño event since the record-breaking 1997-1998 season. The National Oceanic and Atmospheric Administration put the likelihood of a major Northern Hemisphere El Niño at 80 percent. But despite high expectations, the predicted El Niño of 2014 has ultimately fizzled. [...]
