The Not So Hellish Hell Creek

Our second day of prospecting was spectacular as we hiked amongst a rainbow of wildflowers.  There was no shortage of bone either. We spent a couple of hours collecting from a micro site (a sediment layer loaded with tiny bones and teeth). Here we collected fossils of many different species including croc osteoderms and teeth, … Continue reading The Not So Hellish Hell Creek

Over the last year or so I've collected quite a few papers on the subject of Precambrian crustal evolution and sedimentary basins of Peninsular India. I'm sharing the list with links. Many of them are available open access from various outlets. I got my teeth cut in field geology and carbonate sedimentology during my M.S. thesis research. This involved mapping a small area of the

Sinocoelurus fragilis was first described in 1942 by influential Chinese paleontologist Yang Zhongjian (commonly known in English as C.C. Young). The four teeth ascribed to this genus were found in the Kuangyuan Series of the Shangshaximiao Formation in the Sichuan province of China. The teeth date to the

The game developers of Jurassic World cell phone game have modeled an Edestus shark for the game. It showed up as one of the creatures to get past in the tournaments set for this weekend. It is interesting to see how the graphic designer modeled it's teeth in a single row. The real shark is much older than the Jurassic Period. It dates to the upper Middle Pennsylvanian or Carboniferous

I found a number of these round, nut like brachiopods while searching the Bois d'Arc formation in Oklahoma. They are called Sphaerirhynchia lindenensis and seem to have a bit of variability in their features. Overall the shells are rounded to subpentagonal in outline and rectangular to square in cross section. Both valves are convex and have strong, rounded ribs decorating the surface. The margins of both valves are flat except along the anterior margin where the shell develops "teeth" that [...]

Mantell (Feb. 3, 1790 – Nov. 10, 1852), a physician of Lewes in Sussex in southern England, had for years been collecting fossils in the sandstone of Tilgate forest, and he had discovered bones belonging to three extinct species: a giant crocodile, a plesiosaur, and Buckland's Megalosaurus. But in 1822 he found several teeth that "possessed characters so remarkable" that they had to have

Mastodons differ from mammoths in their teeth were used to eat more trees (branches, twigs, bark) while the mammoths ate more grasses. Also mammoths are more similar to today's elephants with their longer tusks and more distinct heads. The mastodon has

Preserved trees that grew 12,000 years ago improve radiocarbon dating calibrations

by Emily Benson   Scientists use radiocarbon dating to determine the age of everything from bone and teeth to seeds and straw. The accuracy and precision of those dates depends on careful calibration. New data from logs unearthed in a small floodplain in New York’s Lake Ontario lowlands will allow scientists to refine the calibrations for a 1,200 year period that occurred about 12,000 years ago, according to Carol Griggs, a

Yes, Nessie had to be in the title. Am I sorry? A little. But not enough to not use it. Colleagues from the University of Edinburgh and myself have described the first Scottish crocodile fossil! It’s from the Isle of Skye, from a time known as the Middle Jurassic, and dates back around 160 million years ago. Based on a partial bit of a jawbone (the dentary), it’s hardly the most spectacular fossil we’ve ever found, but it tells quite a neat story. Based on the features we [...]

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 [...]

For some reason beyond the ken of mortals, the Antlers Formation of southeast Oklahoma has yielded only a small handful of Acrocanthosaurus (Stovall and Langston 1950; Currie and Carpenter 2000), one partial Deinonychus skeleton and a few dozen shed teeth (Brinkman et al.
