Una delle parti più controverse delle
varie ricostruzioni di Spinosaurus è la posizione delle spine
neurali allungate illustrate da Stromer (1915). Tutti concordano che
queste spine neurali siano collocate nella parte post-cervicale della
serie, ma non tutti concordano se queste siano limitate alle vertebre
dorsali, se includano le vertebre sacrali ed eventualmente anche le
Alcune delle differenze più significative tra Spinosaurus B e Spinosaurus C (modificato da Ibrahim et al. 2014, informazioni supplementari).
Evers et al. (2015) hanno puntualizzato
le differenze esistenti tra le ossa comparabili pubblicate di
“Spinosaurus C” (l'esemplare introdotto da Ibrahim et al. 2014) rispetto a quelle illustrate da Stromer
(1934) per “Spinosaurus B”. Secondo questi

L'acceso dibattito innescato dalla
pubblicazione di Ibrahim et al. (2014) si è concentrato
principalmente sulla ricostruzione di Spinosaurus proposta in
quello studio. Tale ricostruzione, come ogni ricostruzione da resti
frammentari, è sempre una ipotesi. Discutere sulle ipotesi è
interessante e spesso divertente, ma

Oscar Mmari (’14) is a Wooster Geology alumnus who did field work in Israel as part of his Independent Study. After his graduation he has had excellent geological experience in Africa and Europe, most involving mining and other resource-related industries. He has kindly given us this account of a field trip he took on August
My latest audiobook consumed during my commute was the story of Napoleon Bonaparte’s (why do we always call him by his first name?) ill-fated expedition to Egypt in 1798. Napoleon brought with him a corps of “savants,” natural historians, engineers, artists, and musicians, charged with documenting the history and natural history of Egypt, and helping built structures and solve problems to make the colony work well. This was the expedition

Lo scorso venerdì 18 settembre, sono
stato a Milano, in visita alla mostra dedicata a Spinosaurus,
organizzata dal Museo di Storia Naturale di Milano, l'Università di
Chicago e la National Geographic Society. La mia visita è stata
molto particolare, dato che ho avuto
Venerdì prossimo, finalmente sarò a Milano per visitare la Mostra su Spinosaurus di cui ho parlato in passato. In quella data, inoltre, Cristiano Dal Sasso e Simone Maganuco parleranno al pubblico della scoperta e della rivalutazione di questo dinosauro.
Earlier in the week, I saw a BBC News story entitled "Online fossil hunters to help comb Kenyan desert" by science reporter Jonathan Webb (8 September 2015). It talks about a British research web site fossilfinder.org to get the Internet's public to help find possible fossils in the Turkana Basin of northern Kenya. Fossils there date back about 6 million years.
I tried it out and did not

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
