The whole atti-tude strongly suggests a spastic distress,possibly brought on by some form ofpoisoning of the central nervous system,from infection or the deglutition of somepoisonous substance. 14. Osteomalacia is evidently the causeof the hypertrophy of the bones of Lim-nocyron potens, an early carnivore from theWashakie Eocene of Wyoming, nearly3,000,000 years old.

The skeleton of Strutbiomimus altus, a small dinosaur from the BeliyRiver series (Cretaceous), Red Deer River, Alberta, Canada, now regarded as ofapproximately the same age as the Judith River series. The unique feature ofthe skull is the total absence of teeth, with a size of skull one-third larger thanthe ostrich and a length of body of about fifteen feet. The position of the skeletonis decidedly that of the opisthotonos which may be regarded as an indication ofdisease. (After Osborn). A beautiful specimen of an osteoma, theonly one known so far, on the vertebra of aKansas Cretaceous mosasaur, was given thewriter by Dr. J. M. Armstrong of St. Paul.The writer expresses his obligations to thegentlemen connected with the above-men-tioned institutions and to Dr. Armstrong.The methods used are a combination ofprocedures in the various lines involved.Microscopic sections, which can be madethin enough for immersion lens study, are material with similar lesions in recent hu-man mat Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.

The Canadian Fossil Discovery Centre in Morden boasts the largest collection of marine invertebrate fossils in Canada. Visitors to the museum not only get to see this collection, but can join a dig in search for more fossils at a 109-acre escarpment property. Photo credit: Robyn Hanson

Dinosaur sand sculptures at the Sand Sculpting Australia "Dinostory" exhibit held at Frankston, Victoria, Australia 2008/2009.The sculpture was the created with the combined efforts of an international team of sand sculpting artists: Karen Fralich (Canada) - children playing in foreground; Peter Bignell (Tasmania, Australia) - Triceratops skull and logo; Martijn Rijerse (Netherlands) - Tyrannosaurus rex scene; Jino van Bruissenen and Christina Mija (NSW, Australia) - background panel.

Greenlandite (fuchsite-quartz gneiss) (2.7 cm across at its widest) from the Precambrian of southwestern Greenland. Green = fuchsite; gray = quartz; a few small, scattered pyrite crystals (brassy gold-colored) are also visible. Attractive greenish-colored gneisses in southwestern Greenland that contain the minerals fuchsite (green) and quartz (gray) have been informally called greenlandite. Fuchsite is a chromian muscovite mica (K(Al,Cr)2AlSi3O10(OH,F)2 - potassium chromium hydroxy-fluoro-aluminosilicate); it is typically encountered in schistose rocks. Greenland greenlandite is part of a 3.8 billion year old, highly metamorphosed succession of rocks. These represent the oldest known supracrustal rocks on Earth (the oldest crustal Earth rocks include 4.03 billion year old Acasta Gneiss, 4.28 b.y. rocks from the eastern Hudson Bay area, and 4.45-4.55 b.y. rocks in the subsurface of Baffin Island, Canada). Locality: undisclosed locality in the Godthåbsfjord area or Nuuk area, southwestern Greenland. Age: Eoarchean boundary, 3.8 billion years.

Geographic and stratigraphic relationships of the holotype EMK 0012 and the Loki Quarry in northern Montana. (A) Regional relationships between the cross-border paleontological sites in the Oldman and Judith River formations along the Milk River and in Kennedy Coulee in Alberta and Montana. (B) Generalized stratigraphic section in the Kennedy Coulee area modified after Goodwin & Deino (1989) and Rogers, Eberth & Ramezani (2023) with the relationships between the Foremost and Oldman formations in Canada and the Judith River Formation in Montana. Relative placements of important taxa in this area are indicated. Position of 40Ar/39Ar dates originally obtained by Goodwin & Deino (1989) are shown in relation to the new U–Pb CA-ID-TIMS date for KC061517-1 by Ramezani et al. (2022). Bentonite ash beds are only 5 to 7 cm thick so they are exaggerated for clarity. Scale bars delineated in map view are indicated kilometers and in meters stratigraphically.
