April General Meeting Presentation - Friday, August 3rd - Starting at 7 P.M. University of MN - St. Paul Campus, Borlaug Hall, Room 335 Noah Anderson will be presenting on...

The Conservation of North American Herps And, in case you missed the July general meeting, here is a recap just for you!

Fossil History of Crocodilians The speaker for July was Dr. Christopher Bruchu, an associate professor of vertebrate paleontology at the University of Iowa in the Geoscience department. His topic was “The myth of the living fossil - Diverse approaches toward crocodyliform history”. Crocodiles are widely considered to be “living fossils”. The common belief is that they have retained basically the same form for millions of years, appearing in the fossil record pretty much as they do today. There had been a few offshoots from the line which show some different traits, but the main line remained unchanged. However, Dr. Bruchu challenges this idea and believes that the line has in fact varied over time just as much as any other group. Initially, when people were trying to classify animals, all they had to go on was what the animals looked like now and what their apparent ancestors look like in the fossil record. This method is strictly empirical; that is, a study of visible physical traits. With the advent of DNA collection and analysis, animals and plants can be compared genetically to determine their relationships to each other. Sometimes this supports the empirical classification, but sometimes it does not. Today, the order of crocodylia consists of three families: crocodylidae, alligatoridae (which includes the caiman) and gavialidae, which are the gharials. One differentiating feature between crocodiles and alligators is the teeth – alligators have a complete overbite, whereas crocodiles have teeth that mesh and a notch in the upper jaw. Both evolved from a common ancestor different from the modern forms that appears to

have both a notch and an overbite; alligators lost the notch and the crocodiles the overbite. Gharials are distinguished by a long narrow snout. With the advent of DNA analysis, there were a number of discrepancies between the genetic and empirical phylogenies. However, Dr Bruchu feels that a lot of the confusion stems just from naming conventions rather than the data itself. When this is cleared up, the trees are almost identical. The only thing that still doesn’t fit is the gharials. More data can be added to help resolve the differences, but it must be added correctly. What it gets down to is morphology vs. molecular data. Just because two species look alike does not mean that they are closely or directly related. The fossil record for crocodylia does back more than 80 million years, and the ancestral groups back to the Triassic period over 200 million years ago. There are many fossils for them as they tend to have a heavy, dense skeleton that fossilizes well. However, there are few complete skeletons; as is common with most fossils, bits and pieces of the skeleton have been found. Although there have been crocodile-like creatures around for millennia, there is a lot of variety to be found. Some have incredibly long noses; some like notosuchus had noses that were very short and pig-like. One, mourasuchus, looked like “a surfboard with teeth”. Some had teeth more designed for crushing rather than tearing. Another, purussaurus, had incredibly large nostrils. Dr. Bruchu says that they are actually large enough for a person to stick their head into the skull and jokingly suggested that perhaps this

The Newsletter of the Minnesota Herpetological Society crocodile inhaled its prey. Pristichampsus had serrated teeth, a flattened snout and hoof-like feet. Others took to the oceans and developed flippers and a dolphin-like fluke. So although there have been creatures in the past that very closely resemble today’s species, there are a great many more that clearly belong in the group but have very different characteristics. The assumption in the past has always been that the ones that look like the extant groups were their ancestors and the others were evolutionary side roads. This is the theory that Dr. Bruchu is challenging; he feels that the real ancestors are some of the “oddities” and that reclassifying the groups will reconcile the differences between the DNA and the morphology. The species sampling will make a difference,

and the data set used must be appropriate for the questions. The skulls should be examined not just for obvious traits like snout length and width, but more subtle characteristics like the external mandibular fenestrae (the hole in the jaw of an alligator) as well as where and how the muscles attach, which varies or can even be absent. Tracing things like brain size is a bit difficult, as the brain of a crocodylian does not fill the braincase in the skull. Next year there will be a gathering in Washington DC, and hopefully if they can get enough people in a room talking it over for long enough, much may be resolved. After all, Dr. Bruchu was able to show several slides and skull drawings proving that Barney was not a dinosaur or a newt, but a fish (and no, I am not kidding about that!)

Looking to meet other MHS members? Help assist the society achieve it’s goals of educating the public? Or just have a good time showing off your herps? Here’s the perfect opportunity! Here’s the deal- Bring your herp(s) to one of the shows listed above, and talk about them. That’s it! You don’t have to be an expert, you’re not giving speeches. Most of the time you will find that people are more than open to hearing about our misrepresented critters. Sound fun? Great! There are just a few requirements: Bring only healthy animals. Make sure you know the basics about your animal; What they eat, how long they live, adult size, cage needs. There is no size limits as long as the handler can comfortably keep control. We do not let viewers pat them on the head and do not allow them to directly hold the animal. If the animals are very young, display in a cage is recommended. Children may participate as long as they have adult supervision.

Board Minutes for May 5th, 2012 The meeting was called to order at 6:09pm. The calendar was reviewed for action items. Ellen read the minutes. Motion to accept the minutes: Chris R; 2nd: Peter. Motion passed. Old Business Adoption Amendment: There was a proposal to change the 1.5 clause of the adoption policy to read as follows: 1.5 Venomous 1.5.1 MHS does not accept venomous animals from the general public. 1.5.2 Venomous animals received will not be placed at the general meeting. Motion to accept amendment as stated above: Heather; 2nd: Chris R. Motion passed.

New Business

Hands-on Trunks: Right now there are 3 trunks. Jan has one and one is usually kept by the Bosman’s, who live on the northwest side of the cities. The third should be placed with someone on the north or northeast side of the cities, to make them accessible as needed. Beth volunteered to keep the third trunk. Fostering/Euthanasia: The number of animals coming in and needing fostering is increasing. Ways of dealing with the surplus were discussed, including renting fostering facilities, euthanizing – how, when and who -and allowing the general public to adopt unplaced animals after their 3 months is up. Motion to adjourn: Ellen; 2nd: Jeff. Meeting adjourned 8:02 pm.

Minnesota State Fair Announcement The 2012 Minnesota State Fair will take place between Thursday, August 23rd, and Monday, September 3rd. On each of these twelve days, the Minnesota Herpetological Society provides animals for an exhibit in the DNR building (located at the corner of Carnes Avenue and Nelson Street). Thanks to this display, visitors to the building can

view six species of native snakes and four species of turtles. Jim Gerholdt, a lifetime member of MHS, graciously allows us to use one of his timber rattlesnakes for the centerpiece each year! Longtime member, John Moriarty, provides four species of turtles for the two display tanks. The other snakes are on-loan from the personal collections of other MHS members. To adequately provide care for these animals, twelve MHS members agree to serve as “Daily Investigators”. It is necessary for a member to check on the snakes and turtles each evening when the DNR building closes. At this time, the enclosures can be opened so water levels in each bowl and aquarium can be maintained, as well as the removal of any feces or shed skins. The DI must arrive at the DNR building no later than 8:50pm to gain access to the animal area. If you are interested in participating, please contact Beth Girard, MHS State Fair Chair, at 612/616-8431 or by e-mail at beth_girard@msn.com
