Fossil Friday – Foerestephyllum

IMG_5395Corals are such an iconic part of the modern ocean, it’s easy to overlook the fact that they didn’t become widespread until the Ordovician Period, 4 billion years after the Earth formed and some 30 million years after the Cambrian Explosion. Continue reading

Fossil Friday – bourbon and geology

2011-02-20a

In a few weeks we’ll be opening our new exhibit at WSC, “Life in the Ancient Seas”, which will include a fair number of specimens from Ordovician rocks in the midwest. In recognition of that event, I’m reposting this post, originally published on my old blog “Updates from the Paleontology Lab” in 2011. Continue reading

Fossil Friday – sunset clam

Asaphis centenaria

At the end of this month WSC is opening a new exhibit, “Life in the Ancient Seas”. A big portion of the staff’s efforts are currently focused on getting this ready, including writing labels for individual specimens; this may be the largest exhibit we’ve ever done in terms of shear specimen count! But sometimes these labels can be difficult to write, as the information is often obscure. Continue reading

Fossil Friday – ceratopsid ilium

On May 17, I posted a photo of the ilium of a ceratopsid dinosaur that we collected in the Upper Cretaceous Menefee Formation of New Mexico. At the time, only the medial surface of the bone was visible; however, WSC volunteer Joe Reavis has been working hard and has now prepped the lateral surface as well. On May 17, I identified the bone as a left ilium, but now that I can see the whole thing, I can say that it’s actually a right ilium.

Organisms don’t exist in a vacuum. The whole concept of an ecosystem emphasizes the interactions between an organism and its environment, including with other organisms. A large organism like a mammoth can have wide-ranging effects on numerous other organisms, even after its death. Continue reading

Today’s Fossil Friday specimen comes from the Pleistocene camel Camelops hesternus, a taxon we’ve featured several times on this blog. But this specimen is special because of where it was found – in Joshua Tree National Park. Continue reading

Fossil Friday – ceratopsid illium

ceratopsid ilium

Last week for Fossil Friday, I posted the sacrum of a ceratopsid, a large horned dinosaur related to Triceratops. The sacrum is a series of fused vertebrae to which the hip bones attach. Today, I want to show you one of those hip bones from the same ceratopsid individual.

Horned dinosaurs were one of the most successful groups of dinosaurs in the Late Cretaceous of western North America. Known as ceratopsids, these rhino- to elephant-sized beasts brandished horns, spikes, and frills on their massive skulls.
