Apparently TPI is the new home for the small turtles of the Niobrara chalk. We've already prepared, molded and cast our tiny Chelosphargis advena, Prepared a new Prionochelys matutina, and show prepped a nice Toxochelys latiremis that we discovered this past spring, all with nice skulls.Our Prionochelys matutina specimen from MU5 (Coniacian)You'd think that we would be content with our fossil turtle stash, but no. You can never have enough of these little guys. This week we prepared from start [...]
After bringing live animals, exotic insects, chemistry demos, and more to over 500 area schools and community organizations last year, the Houston Museum of Natural Science’s Outreach Programs are ready to hit the road in 2015! It takes quite a village … Continue reading

Birds are a phenomenal story of evolutionary success. As modern-day dinosaur descendants, they occupy almost all environments and ecosystems around the globe, and are truly animals that capture our imaginations. However, how did they become so diverse, both in number and form? This is something only the fossil record can divine for us. Birds first appear in the Middle to Late Jurassic of China and latest Jurassic of Europe (hello, Archaeopteryx), around 160-150 million years ago. Their first [...]
Once a hard shelled animal dies it's shell often lies around on top of the muddy bottom until it gets buried. While it is exposed it provides a hard surface for many other encrusting animals that otherwise would not be able to establish themselves. Today I have two examples of trace fossils that were left on the interior surfaces of pelecypod shells from the Devonian aged Panther Mountain formation in NY.First up is this shell which may be an Actinodesma erectum or another species. It's hard to [...]

Jurassic in OxfordshireElizabeth DevonSaturday 21st March Kirtlington Quarry SSSI - go back in time to a Jurassic environment similar to the Florida Everglades today. These conditions attracted many animals, and the quarry is famous for its rich diversity of fossils. Evidence for the presence of nearby land is provided by the presence of fossil wood, freshwater algae and crustaceans, disarticulated dinosaur skeletons and very rare mammal fossils. It is the richest mammal-bearing locality of [...]
Because of climate change, spring, summer, fall and winter in the temperate zones are all arriving on average 1.7 days earlier than they ever have before. The changing climate with its more extreme weather is affecting many plant and animal species, disturbing their habitat and disrupting ecosystem functioning. How will plants and animals deal with these
Anurognathus ammoni makes itself like a tree, but doesn't leave. Prints are available.Last week I unceremoniously dumped several revamped pterosaur images on the blog after they were prepared for a talk on one of my favourite topics - pterosaur functional morphology and biomechanics. Turned out that I wasn't quite done tinkering with old images however, because another piece - above - was set for 11th hour reworking. It shows one of the subject taxa of my talk - an anurognathid pterosaur - [...]
In 1959, off the southern coast of France, a tuna boat hauled up a largetooth sawfish. The catch
When I considered how I might become a fossil, I mostly thought about the environment I’d have to
The next up on my tour of the National Parks in pictures:Pony Express National Historic TrailLast year my family and I headed out to find some geodes in the Utah desert. Along the way we traveled along the Pony Express Trail. Although this trail spreads on through many states, here is a small portion of it, near Dugway, UT. View looking east, as we passed through Dugway Pass.This post marked the location of the Pony Express, which ran from 1860-1861.Recreation of the Simpsons Springs [...]
The La Brea asphalt seeps are famous for the predators found entombed there. Dire wolves and the sabercat
To identify, understand, and manage soils, soil scientists have developed a soil classification or taxonomy system. Like the classification systems for plants and animals, the soil classification system contains several
Now that we’ve collected soil samples, we need to extract and identify the organisms living in the soil. We also need to measure the chemistry of the soil to understand the organisms’ habitat. For the past few days, we’ve been working quite a lot in the lab.We first preserve part of the soil to measure the bacteria and fungi back at home in the U.S. We separate some of the soil into a vial and add a solution that preserves the bacteria and fungi. These vials will be sent home and analyzed [...]
We STILL can't get to our field sites. Mars Oasis is too cloudy for the plane to land. Maybe tomorrow!Instead, today I helped the marine biologists. There are many marine biologists at Rothera Station that study the invertebrates living on the bottom of the ocean. To do their research, they have to scuba dive in the bay that borders the research station. The cold water is their first danger, so they wear protective suits. There are a couple other dangers they must avoid, which are leopard [...]
I’ve spent much of my weekend writing about Jurassic World. I won’t rehash the details here – you
Here are a few pictures from a three-day cruise in the Galapagos Islands. This was my 7th or 8th time there. I just love the desert landscapes and wildlife.Tall opuntia cactus on Santa Fe Island. Many of the islands have variations of this species of Opuntia echios.Opuntia echios (var.) Found on Santa Fe Island.Many of the islands also have endemic iguanas (Conolophus subcristatus). You cna read more about them here.I think these are the most interesting of the many animals to be seen in [...]
The view north from Logan Pass in Glacier National Park
Make no mistake about it. Glacier National Park is one of the most spectacular parks in the United States, and indeed is one of my favorite places on planet Earth. That said, it's losing something important, and the change is profound.
How many animals are in this picture?
When I was a child, I loved museums, but I knew there was
As pointed out to those who step aboard the JR, animals are all over the boat. You just have to look.
If you walk along the catwalk to the doghouse, you might overhear the crew talking about Bigfoot stuck near the mousehole. Rather than tying yourself in a sheepshank wondering what they are talking about, bone up on your drill ship lingo.

The Ediacaran saw creatures grow
Diversify as animals evolved.
But Cambrian descendants do not show
A lineage, preserved or else dissolved.
A missing fossil yearns to be dug up.
The flinders ranges burn to tell their tale
Trace fossils, both a spicule and a cup
Mean evolutionary theories can prevail.
once a sponge
With opaline supports to hold it flat
Leave it to echinoderms to take even the best known of animals, like a sand dollar, and make it even STRANGER than you could have thought!!
But first things first. Sand dollars are highly modified SEA URCHINS that live on sandy bottoms, mostly in shallow tropical to temperate water places. Please make a note of it. (or go read this post here!)
Most sand dollars are either kind
