New bird sighting added to list

9 February 2010. Edmonton, AB, Canada.

1115. This morning, as I walked out of Dr. Mark Wilson's systematics lecture towards the Biological Sciences Building on the University of Alberta campus, I heard an unmistakenable call coming on one of the tree branches high above me...

It was a warm and energetic song of the Eastern Phoebe, Sayornis phoebe, and not the dry cracking call of the black-billed magpie that one is accustomed to during the northern winter. Phoebes are tyrant flycatchers (Family Tyrannidae) that catching insects in mid-air with acrobatic maneuvers.

They are also the sure signs of spring in this part of North America; in central and northern Alberta and other regions of the northern plains, these insectivorous birds are summer visitors, leaving for warmer southern areas at the end of each fall. Their call this morning is a welcome one, as snow still covers the lawns on campus, but no longer is the wind chill bitter and sharp. Warmer weather is upon us, and longer days are leading us into the green season, a change not so distinct in California!

Hooray for spring!

New study by LACM paleontologists

29 January 2010. Natural History Museum of Los Angeles County.

A study of new material of the nimravid ("false sabertooth") Barbourofelis whitfordi by LACM paleontologists has just been published in the January 2010 issue of the Journal of Vertebrate Paleontology.



This paper describes an almost complete dentition of the most basal species of the last-remaining nimravids in North America. Barbourofelis first appeared in North America during the early Clarendonian North American Land Mammal Age (NALMA), and persisted until the Hemphillian NALMA. The approximate duration of the genus is 5 million years, between 12 and 7 million years ago.

The new fossils were discovered in the Dove Spring Formation, located in gorgeous Red Rock Canyon State Park in the Mojave Desert of southern California. The inspiration and awe that majestic California State Parks give to us rival their rich scientific resources! Paleontologists are still being humbled by what the ground hides beneath its surface, even after more than 100 years of geologic and paleontologic study in the area.

The discoverer of the new fossils is a long-time museum staff, associate, and supporter Mr. Kamaron Sardar, also a protector and server of our city.

New Yorker in Beijing: the home of Walter Granger (1872-1941)

20 January 2010. Edmonton, Alberta, Canada.

While reading about the American paleontologist Walter Granger today, I made a small discovery that sent my nostalgia flying through the streets of Beijing where I roamed in 2009.

A publication by Vincent Morgan and Spencer Lucas in the New Mexico Museum of Natural History Bulletin in 2002 narrated the life of Walter Granger, the chief paleontologist of the Central Asiatic Expedition (see earlier entries such as this) of the American Museum of Natural History, whose expeditions in Inner and Outer Mongolia made some of the most spectacular fossil discoveries of the time (dinosaur eggs, Velociraptor, the giant Paraceratherium, etc.).

In that publication, Morgan and Lucas (2002) figured Granger's call card, which printed on one side:

"Mr. Walter Granger
Paleontologist, Third Asiatic Expedition of the American Museum of Natural History, New York, U. S. A."

and on the other side, in Chinese:

"美国纽约亚美利坚天产博物院第三次派赴亚细亚洲调查古物格致家
谷蘭階
寓北京东城弓弦胡同"


The first line was Granger's title and association, and the second his name. The third line was the street where he was housed. It was this last line that gave a clue as to the present day location of this historical residence.

The narrow alleys of imperial Beijing were called "hutong", which are too narrow for modern automobiles but passable by horse-drawn carts and pedestrian traffic. Many hutongs had identical names, but on Granger's card it was indicated that this particular hutong, "Gongxian Hutong", was located on the East City district of Beijing, or Dongchengqu.

As of 2009, this hutong is still adjacent to the China Art Museum, a prime piece of property in modern Beijing that is adjacent to the northeast wall of Gugong, the Forbidden Palace.

On more than a few occasions, we (my fiancée and I) passed the China Art Museum and the adjacent hutong on our way to the shopping street of Wangfujing, a tourist trap, unknowingly glancing at the treed alleys from cable bus line 111 at what was the residence of Granger; a paleontologist who made history with the discovery of Chinese fossils to the north, where our IVPP paleontologists work today.

The passage of time washes away the minute and the routine, but leaves echoes in its wake.
