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

Africa possibly doesn’t spring in your thoughts when planning for a seaside vacation whilst the first location you’d select, but there are lots of excellent reasons. Cape Area in Africa has up to lately been “the” location to visit in the event that you desired to visit Africa and revel in the rest of the […]

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.
Here at Geotripper I usually write about my travels, geological and otherwise. I feel inordinately lucky to have a job that allows me to travel a lot, introducing my students to the incredible world that lies beyond the borders of their town. 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
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 [...]
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
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. [...]

Christopher Barry was the winner of our Blog Competition in 2012, with this article on safe drinking water in Burkina Faso. Christopher was privileged to be able to visit Burkina Faso prior to writing this, a very rural country where a great number of people are dependent on drilled wells with hand pumps for clean water. In Ouagadougou he met Mark Collier, where they talked at length about hydrogeology in the country. Now a PhD student at the University of Birmingham, Christopher Barry is [...]
Celia Willoughby, UCL Geography student and GfGD Ambassador, writes about a recent event… Wednesday 19th November, saw the first UCL GfGD lecture of the year, taken by guest speaker Prof. Richard Taylor. Professor of hydrogeology in UCL’s Geography Department, his most recent focus of research is the study of groundwater, and the effects of climate change on groundwater supplies. The application of scientific skills to facilitate global development is key in Prof. Taylor’s [...]
Federico Fanti e nuovi resti di Tataouinea hannibalis (Fanti et al. in review: MEGA SPOILER!!!!)
La mia quasi totale assenza dalla
blogosfera durante questo mese ha vari motivi. Di questi, quello più
concreto sta per entrare nel vivo. Venerdì prossimo, partirò per
Tataouine, nel sud della Tunisia, assieme a Federico Fanti, Luigi
Cantelli ed alcuni studenti del dipartimento di Scienze
The genus Homo, to which we belong, was the first to leave Africa and explore the world. Homo erectus, one of our ancestors, explored Asia and Europe as early as 1.8 million years ago. However, one huge landmass was left … Continue reading
Louis and Mary Leakey
From Today In Science History:
Leakey (Aug 7, 1903 – October 1, 1972), an archaeologist and anthropologist, was born in Kabete, Kenya, of English missionaries parents. Leakey was largely responsible for convincing scientists that Africa, rather than Java or China, was the most significant area to search for evidence of human origins. Leakey led fossil-hunting
Post conclusivo della
serie dedicata alle nuove scoperte relative a Spinosaurus.
Il nuovo esemplare
riferito a Spinosaurus ha permesso non solo di rivalutare l'enigmatico "Spinosaurus B" ma anche di raffinare
le controverse stime sulle dimensioni di questo dinosauro. Il nuovo esemplare
include varie ossa confrontabili sia con l'olotipo di Baryonyx
che con l'esemplare originario descritto da

prossimamente, ma un recent commento di Mickey Mortimer mi ha indotto
a pubblicarlo ora.]
Perché Sigilmassasaurus è
stato per quasi venti anni un dinosauro così enigmatico, e solo di
recente riconosciuto in modo inequivocabile come essere un sinonimo
di Spinosaurus? L'enigma si Sigilmassasaurus deriva
