What comes to mind when you think of dinosaur interaction? Large carnivores chomping on unsuspecting little ornithopods? Ceratopsians jousting for their next mate? Large hadrosaurs tenderly mothering their cute newborns? There are many possible images of community-level dinosaur interactions, and there is a host of evidence out there that take dinosaurs beyond the bones and breathe new life into h ...[Read More]

Dinosaurs of a feather?
Feathered dinosaurs might not still be the new boys in town in the fossil world, but there’s still a tonne of cool research being done on them. One of the main fields is trying to figure out if different species were capable of powered flight, like in most modern birds. The recent finding of Aurornis xui appears to have confined the ability to fly just to a single feathered lineage, the one leadin ...[Read More]

Imaggeo on Mondays: Mendenhall Glacier
Much of the Mendenhall River Basin is glaciated; indeed, the river flows out from under a glacier in the northern part of the valley and into a lake. This glacier, rather aptly, is known as Mendenhall Glacier, a 19 km long lake-calving monster in Alaska, USA. Meltwater from this glacier makes up the primary source of water for Mendenhall River, although several creeks also contribute to the flow, ...[Read More]

New Opportunity – Hazard Factsheets
Jane Robb, GfGD Communication Officer, writes about a new and exciting opportunity for GfGD members… For many of our followers the opportunity to get involved in international development as a geologist, or at all, is difficult. One of GfGD’s core purposes is to help change this at a UK level, to make sure that good geoscience – and geoscientists – can contribute to good de ...[Read More]

GeoCinema Online: Oceans
This week on GeoCinema Online, we’re taking a look at all things ocean, bringing what few people see straight to your desktop – or, for that matter, any other shiny viewing device you may posses! Take a dive and find out what plankton get up to in the microscopic world beyond our vision, what corals and communities lie in the cold deep and how oceanographers are working to better under ...[Read More]

Friday Photo (85): Wildlife in the Field – Caterpillar Wiggles Across Old Burrows
This unusual looking caterpillar is working his way across the Houjiashan Formation on the North China Craton. These rocks formed in the lower Cambrian, and are crossed with burrows formed by some of the earliest motile animals. (c) Geology for Global Development 2013

Guest Post – Mike Power – Using surficial geochemistry to detect buried mineral deposits
Finding the next big mineral deposit is a dream of many geologists past, present and future. However, in the past hundred years or so, many of them close to surface have already been found and developed. This is because they can be found relatively inexpensively by traditional methods such as geochemical surveys, shallow geophysics, drilling, and a lot of luck. In the 21st century, mineral explora ...[Read More]

How did birds get their wings?
How many fingers do you have? Hopefully, 5. Do you think that’s the normal condition for all animals? Do you think that’s air you’re breathing right now? … OK, so I watched the Matrix last night, but still, do you think all tetrapods (dudes with 4 feet, including you, and anything else with four flippers, wings, or feet) have 5 digits on each limb? Actually, there’s a pattern within tetrapods of l ...[Read More]

Dust in the desert: Measuring it is only half the battle – Part 1 of 3
Fieldwork is vital to understanding all sorts of Earth processes, but that doesn’t make it easy! James King, a researcher from the University of Oxford, describes what it takes to set off on a scientific expedition… Although the classic text on sediment transport by wind by Sir Ralph Bagnold was written way back in 1941, the mechanics of dust storms and their effects on the climate are still ...[Read More]

Upcoming GfGD Placements
July will be a busy month for a few GfGD members – as they undertake geoscience-development based placements with a variety of hosts. Below we introduce you to the three students, and give them the chance to say a few words about the opportunity they’ve been given. Each student will be preparing a report on their placement, which will be made available on our website. All future placem ...[Read More]
