what theropod family is the strongest(at parity)? Is it:
all theropods are represented by the “best” of there group at 32 feet long Abd how ever much they’d weigh at that size
the early tyrannosaurids? these vicious t.rex predecessors relied in speed agility and arm power to kill there prey abd fight rivals. They had long narrow
Not much to say this time – the pictures tell the story for now. It was a pretty transcendental experience, as I imagine it must be for anyone who loves dinosaurs, or has a pulse. A huge thank-you to Dan Chure, the Park Paleontologist for the Monument, who conveyed us safely up and down the
The Redi-Rock Design Resource Manual or DRM has everything you would need to design a Redi-Rock retaining wall, including block sizes, design charts, construction details, and setback options. The manual also includes case studies and an installation guide and more. Watch the video below for more info.

It's winter, and it's cold outside. I won't be in the field for another six weeks, so for now I'm reveling in the memories of this last summer, a journey through the Southwest states. We started our field studies trip at Hole in the Wall in the Mojave National Preserve, and after spending the morning hiking in Banshee Canyon, we hit the road and moved on to the state border with Arizona.
Christmas is over and suddenly the snow and blizzards aren't so fun any more. I find myself dreaming of warmer places and times, including a great journey we took last summer across the southwest with my students. Since my current travels are over until February, I'm going to travel through the archives to check out some marvelous geology along our southwestern tier of states: Arizona,

I’m fifteen days into NaNoWriMo, and have written twenty one thousand words. That’s a world record for me, although I won’t hide that I’m jealous of people who have already broken fifty thousand. Yes, I am a little bit behind target, but I’ve had a rather demoralising experience. Not because of any incidents in real

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 [...]
When you compare the previous brachiopod I posted about, Rhytistrophia beckii, to today's fossil, Leptaena rhomboidalis there are some key differences. Both are large shells that are semiellipical (half moon shaped) to subquadrate (nearly square) with straight hinge lines. The valves of both shells are nearly flat but the margin of the shell in L. rhomboidalis is turned 90 degrees from the regular shell surface all along the edge. Another distinguishing feature is the somewhat regular, [...]
View of Lawson Syncline looking obliquely along strike (SSE) from an unnamed peak SW of Mount Inflexible, Kananaskis Range, Alberta. The axis of the syncline forms the bottom of the valley and plunges slightly toward the south. The syncline is in the hanging wall of the Sulphur Mountain Thrust sheet. On the right side of the photo, beds can be seen dipping to the right (west) in the ridge the

Now that, faithful readers, is a monument to evolution and its endless forms most beautiful. I’m talking about the wall of ceratopsian skulls at NHMU, of course, not the back of Brian Engh’s head (bottom center). If you don’t know them all on sight (yet!), here’s a cheat sheet. I goofed on a couple myself:

As I've said, all pithy comments now go in my g+ collections. I can't help it if I'm the only one on this. I've followed every Google Titanic to the bottom, and the same goes for this. That's what happens when anti-social super-nerds try to take over the world.
You can't do full articles on social media, so the blog has to stay for a while. I throw these over the wall,
William Smith’s geological map of England and Wales turns 200 this year. It was first published just eight years after the foundation of the Geological Society in 1807. A copy of the map has hung on the wall of the … Continue reading
Students experimenting with an Emriver Em2 geomodel.There's nothing quite as cool as running an Emriver model next to an actual river! It's a fantastic way to teach fluvial geomorphology.Our Em2 and Em3 models are designed for portability, and you can use them just about anywhere. For field sessions or spots without easy access to wall current (or "mains power" in the UK), you can use a 12-volt battery.While we supply a battery power hook-up kit, we do not supply batteries. They are best bought [...]
One last post from my September trip to Greece. Here’s a look north along the inside wall of the central caldera of Santorini, taken from the deck of the Santos Winery. It’s not hard to imagine the volcanic edifice that filled the space to the left (west) prior to The Big
So for years we'd go to a Greek restaurant and marvel at the tender octopus. We'd ask them how they do it, and they would smile slyly, and say it's a secret.
So, began the Great Research. Everybody had their own secret, like throwing the octopus at the wall, or soaking in lemon juice. None of which worked for us. We could only buy the cheap frozen octopus in tubes at the
On our last day on Mallorca, we drove to Alcudia, an old town on the north side of Mallorca. There we walked around and within a perfect old town surrounded by a wall and a moat. The Church is nearly 500 years old, and the houses seem as old. Probably the town subsisted in the
While exploring an old coal strip mine in Gilberton, PA I noticed that there was an exposed wall of rock that used to be covered in overburden. The wall was relatively smooth but had some grooves in it. Upon closer inspection, the grooves turned out to be the impressions of tree roots called Stigmaria. Since these are roots, and they appear to have been preserved in situ, makes me think that the exposed rock is a Paleosol or fossil soil horizon.I encourage you to click on the photos to [...]
Esteemed readership, I’ve got a mystery for you. What are these white lines, inclined consistently at a high angle to bedding? I picked up this sample below the “Wall of Death,” on the trail from Wapta Lake below Mount Wapta, en route to the Walcott Quarry of the Burgess Shale. The “zebra-striped” rock is of the Eldon Formation of the Cambrian section in Yoho National Park. At first, I thought

I'm sure most are familiar with the parable of the blind men and the
elephant. Several men investigate an elephant, but each touches a
different part, so one describes it as being like a snake (the trunk), and others as a
wall (the body), a rope (the tail), a fan (the ear), or a
tree (the
Every now and then I come across a wall or a garden boulder that’s so beautiful I have to take a picture. Such was the case with this serpentinite specimen on or around Huntington Street. This is near Oakland’s great serpentine patch, and it likely came from
