laelaps | October 26, 2007Actually, I don't believe in "spooks," ESP, alien abductions, or much of the other paranormal rot that crops up so often this time of year, but apparently 24% of 1,013 polled adults do. While I take issue with surveys asking a relatively insignificant amount of people their opinion and then projecting those numbers on the whole of the population, I have run into many people who have some, erm, interesting ideas about rather ordinary phenomena. I've been told that cats can detect human souls, that saber-tooth cats were aquatic predators and bit their prey sideways, that there are living…
laelaps | October 26, 2007Just a quick reminder that the next exhibition of The Boneyard will be going up tomorrow at the Hairy Museum of Natural History, so be sure to get all your paleo (or palaeo, if you prefer) oriented links to me or Matt soon! If you need some inspiration check out Matt's fantastic artwork and discussion on phytosaurs, a group that often doesn't get the attention it deserves.
There's some good opportunities for some cross-over posts coming up as well, as the next edition of The Accretionary Wedge is fast approaching, and it's host (Kevin Z of The Other 95%) has asked for submissions about "…

Yesterday my friend Julia commented that one of the best times to visit a museum is in the late afternoon during the winter, and these two photographs will give you some idea why. While the fourth floor of the AMNH is usually bathed in natural lighting during most of the day and artificial lighting from above during the evening, there's a few minutes during the winter months while the sun is getting low in the sky but the overhead illumination hasn't come on yet, a time when shadows sweep across the ancient bones. These two photographs of the "Bear Dog" Amphicyon were taken during that short…
laelaps | October 25, 2007I have to admit that I've been somewhat lazy when it has come to sharing my thoughts on my current reading material since I moved to ScienceBlogs. On Laelaps Mk. 1 I would usually update every few days on what I was reading and what I thought about it, but since I've started writing here I've completed several books and haven't said very much about any of them. While this post is not going to be a massive offloading of knowledge gained from my extracurricular reading, it might at least offer up some suggestions for those looking for some new reading material;

While I love to visit the zoo on warm summer days, I usually don't come home with many good pictures, and the reason why can be summed up in one word: Strollers. Anyone who's visited a museum, zoo, or other such institution with me knows that the never-ending sea of strollers is pretty high on my list of pet peeves, and on at least one occasion the shuffling mob gave me a migraine and sent me off home. There is an easy way to avoid this, however; visit in the wintertime. The above photo is of Zeff, a 14-year-old female Amur Tiger (Panthera tigris altaica), taken right around 10 AM on a cold…
laelaps | October 24, 2007I was planning on putting up one of my patented mega-posts this evening, but unfortunately I just don't have it in me at the moment. It's based on a presentation I made today involving scavenging and early hominids, and while I'm sure some of you will be able to make the right connections (especially if you're familiar with the work of a certain Rutgers alum) here's a video of a certain behavior exhibited by one of my most favorite big cats, the Leopard (Panthera pardus), that'll prominently figure in tomorrow's discussion;

Sol: I give up.
Abe: A herring.
Sol: But a herring isn't green.
Abe: So you can paint it green.
Sol: But a herring doesn't hang on the wall.
Abe: Put a nail through it, it hands on the wall.
Sol: But a herring doesn't whistle!
Abe: So? It doesn't whistle.

I have never heard sounds come out of a dog like the kind that I've heard out of a pack of excited African Wild Dogs (Lycaon pictus), the individual pictured above being a member of a large group kept at the WCS-run Bronx Zoo. While their species once ranged over 39 countries and their numbers were estimated as being as high as 500,000, today there are only 3,000-6,000 individuals left in a handful of countries, pressure from predator competition, disease, and killing by farmers/livestock owners make life very hard for these unique dogs. Indeed, they differ from all other known canids in…
laelaps | October 23, 2007Creationists have been strangely quiet today, their silence all the more odd because it's Bishop Ussher Day! According to Young Earth Creationist dogma the world just celebrated it's 6,011th 6,010th birthday (or a formless, empty Earth just celebrated it's birthday, the job not being finished until a few days later, of course), the creation week beginning the night prior to October 23, 4004 B.C. We know this is preposterous now, of course, but in Ussher's time figuring out the date of the Genesis narrative was big business, many theologians using various sorts of numerology in an attempt to…

Regardless of whether it was gradual or happened in a geologic instant, non-avian dinosaurs went extinct by approximately 65 million years ago, but the question of what they might be like today had they survived makes for some entertaining fiction. Most of such imaginary works are set on isolated islands or plateaus, "Lost Worlds" that have provided a refuge for dinosaurs (the most spectacular and enjoyable example being Weta Workshop's companion book to Peter Jackson's remake of King Kong entitled The World of Kong). Still, many of the dinosaurian hideaways do not take evolution into…

A male Amur Leopard (Panthera pardus orientalis) at the Philadelphia Zoo. To the best of my knowledge this animal is not involved in any breeding or conservation programs.
According to LiveScience, a female Amur Leopard (Panthera pardus orientalis) was captured, examined, and released by WCS workers this week. The leopards, being among the most endangered of big cats and estimated to number less than 40 individuals in the wild, are most likely inbreeding to continue their population, a problem that could have devastating long-term repercussions. While it is not clear whether the problem is…

Yesterday's photographic subject, the cougar (Puma concolor), has plenty of common names by which it is known by (some of which are better than others), and the White Nosed Coati (Nasua narica) is another mammal that is known by many other monikers. Pizote, Antoon, and Harrington all sound more like the names of places rather than a long-nosed member of the Family Procyonidae (which also includes raccoons, the Kinkajou, and Olingos), but that is precisely what they are. One should also be mindful that there is at least one other species of coati, distinct from the Pizote, being known as the…

laelaps | October 22, 2007This past week I managed to read Peter Dodson's very helpful book The Horned Dinosaurs from cover-to-cover (in addition to finishing some books on Megalania, dinosaur reproduction, philosophy, etc. A massive book review is forthcoming), one of my most favorite sections being where Dodson walks the reader through reconstructing a Chasmosaurus skeleton bone-by-bone. Oddly enough, I came across the a YouTube video of a self-assembling Chasmosaurus skeleton (embedding was disabled for this video), although unfortunately for curators I have not known skeletons to acquiesce to fully leaving their…
laelaps | October 22, 2007Unfortunately, I didn't get to attend to the annual SVP Meeting in Austin, TX this year, and I can hardly wait to hear about all the interesting talks and papers from those who attended. My curiosity as to the proceedings has been mildly sated, however, by a news report about one of the interesting discoveries announced at the convention; a mid-Triassic (225 Ma) track found near Melbourne, Australia that has been attributed to a theropod dinosaur.
The 14cm-long tracks seem to indicate the presence of a theropod (or, as Zach has pointed out, some as-yet-unknown bipedal crurotarsian) that stood…

An artist's reconstruction, released by the National Museum of Brazil, of the paleoecology inhabited by Futalognkosaurus (left). It is being menaced by Megaraptor, now known to be a tetanuran theropod.
For quite some time it was thought that after the Jurassic period the massive sauropods that roamed North America were all but extinct, a radiation of ankylosaurs, ceratopsians, hadrosaurs, and other ornithischians becoming the primary herbivores in place of the massive long-necked saurischians. At least one genus did hang on until the Late Cretaceous, the titanosaur Alamosaurus sanjuanensis…

Cougars (Puma concolor), while currently ranging from Canada to the Andes Mountains in South America, still inhabit only part of their former range. Before European colonization, the big cats ranged from coast-to-coast in the U.S., the eastern populations being wiped out with the exception of a small population in Florida. Some have suggested that the cats may eventually make a comeback and reclaim their previous ranges, potential sightings popping up every now and again in Pennsylvania and other states, but by and large if you want to see a cougar and live on the east coast of the U.S. you…

Yesterday's photo of Tai Shan received so many positive responses I thought I would put another one up. Getting these shots could be a little difficult at times, however, (warning: bad pun ahead) as it was definitely pandemonium around the enclosure when the young bear came out. His parents Mei Xiang and Tian Tian certainly didn't get as much attention, but they also were not as active or curious as their offspring. If you want to look in on the pandas yourself the National Zoo has a Panda Cam that will allow you to do so.

I knew this movie was going to be painful, but Supercroc makes last week's film (Raptor Island) look like classic American cinema by comparison. I'm actually surprised that the film was not called "The Thing That Ate Los Angeles," although the film's super-sized antagonist seemed to accidentally step on/fall on its victims rather than consume them. At least it was short; mercifully, anticlimactically so.
Playing with relative sizes of organisms to make human beings helpless is a classic technique in science fiction and horror films, most notably seen in pictures like 1957's The Incredible…

As I mentioned in the description of yesterday's "Photo of the Day," when I visited the National Zoo I wanted to make sure I got there especially early, and this Giant Panda (Ailuropoda melanoleuca) cub is part of the reason. Any exhibit that holds a giant panda, especially a baby one, is going to get swamped by visitors so I wanted to make sure I had a chance to get some decent shots (although I didn't know that the pandas would not be let out until 10 AM so I had a bit of waiting to do). This particular individual is a 2 year old male named Tai Shan, the offspring of Mei Xiang (the mother…
