PSEUDODONTORNS: CALVERT CLIFFS' BIG BIRDS by Matt Andrea Saturday, April 4 was a classic spring morning--crystal blue sky, temperature in the lower bOs--perfect for fossil-hunting at Calvert Cliffs. My Tidelines tide calendar indicated that low tide at Chesapeake Beach would be at 10:51 a.m., so I threw my waders into the trunk of my paleomobile and headed for Randle Cliff. When I got to the beach I was alone and my mind was on BIG TEETH. I walked south to the end of the beach, waded around the treefalls and cliffs, and began inspecting the mini-beaches that appear sporadically between Brownie's Beach and the Randle Cliff Naval Station. It was there that I had my first encounter with BIG BIRD--not the friendly character of Sesame Street fame, but rather a bone fragment lying in the sand, unlike any I had previously found. It was 2 1/2" long, 1/2" wide for most of its length, and very porous. At one end, where the bone was 1" wide, there were two rounded nubs separated by a smooth depression. At the other end was a jagged diagonal break, filled with typical blue-green Calvert sediment. I agitated the bone in the water to wash off the sediment, and then discovered that it was hollow. The bone's general shape, the jagged break and the hollow interior were reminiscent of a broken chicken bone. This was pretty neat, I thought, and I couldn't wait to show it to Dave Bohaska. The opportunity for "show and tell" came the following Saturday. I took my bone to the CMM Fossil Club Annual Meeting at Matoaka Cottages. Dave looked at it and said, "Definitely bird." He asked if he could take it back to the Smithsonian to have the ornithologists look at it. On April 15, Dave called me at my office to inform me that my specimen (which the Smithsonian wanted to keep) was the proximal end of the scapula of a large species 1 of pseudodontorn. I gasped, "A what?" He patiently broke the name down into its component parts: pseudo=false; dont=tooth; ornis=a bird. He asked if I had ever seen the large bird skeleton hanging in the Fossil Hall's "Life in the Ancient Seas" exhibit. I confessed I hadn't. He invited me to come to the Smithsonian to see that and other pseudodontorn specimens in the collection. I asked if he was free that day. He was, so I cancelled my lunch plans and walked across the mall to the Museum of Natural History (10 minutes from my office at l'Enfant Plaza.) Before meeting with Dave, I went to the Cenozoic exhibit of "Life in the Ancient Seas." And there it was--hanging from the ceiling --a reconstructed skeleton of the largest flying seabird that ever lived, wings outstretched in a gliding position, its enormous "toothed" bill open as if to snatch its prey. How could I have missed it?! Beneath the flying skeleton were a number of fossil bones, including an ulna, humerus, articulated vertebrae and skull from Oregon; a bill with "teeth" from California; and a "toothed" bill tip from Maryland donated by Wally Ashby. The exhibit explained that pseudodontorns were related to pelicans and boobies, that their wings were designed for gliding rather than flapping, and that their pseudo-teeth were projections of bone from the jaws rather than teeth of dentine and enamel. Dave showed me other specimens from the Calvert Formation, and I noted that many had been found and donated by Wally Ashby. Dave also showed me bones of an Oligocene pseudodontorn found near Charleston, S.C. These remains, consisting of wing, leg, and skull bones, are the largest and most complete found to date, and one of the primary sources for the reconstructed skeleton in the "Life of the Ancient Seas" exhibit. Just befo~e I left the Smithsonian, Dave introduced me to Ken Warheit, who has been studying pseudodontorns for a number of years. Re4arding my specimen, Ken said, "Nice bone--please find us some more like that!" After this encouragement, I wanted to learn more about these phenomenal birds. I phoned Wally Ashby and Dr. Storrs Olson, a curator of the Smithsonian's Division of Birds. They sent me copies of press releases, newspaper articles and old issues of The Ecphora (#10 & #11). I visited Wally Ashby at Scientists Cliffs, who showed me areas in Beds 12 and 13 in the Calvert Formation where many of his specimens were found. Finally, I visited Dr. Olson at the Smithsonian. He explained that pseudodontorns are in the same order as pelicans, boobies, gannets, frigate birds, and cormorants. The common characteristic of these birds is that all four of their toes are in the web. The term "pseudodontorn" is commonly used as the name of a family of birds that appears to have lived through most of the Tertiary Period, from the Paleocene/Eocene to the Pliocene. Their remains have been found in such diverse areas as France, England, the Caucasus, Nigeria, New Zealand, Japan, Seymour Island (Antarctica)~ and, in the U.S., Maryland, Virginia, the Carolinas, Oregon, and California. According to Dr. Olson, three distinct genera of pseudodontorns have been identified. The earliest genus, Odontopterix, appears 2 in the Paleocene/Eocene of England. The genus which inhabited the Northern Pacific is known as Osteodontornis. The genus which lived in the Atlantic and South Pacific is called Pelagornis. Dr. Olson said there are probably three distinct species of Pelagornis in the Maryland Miocene, ranging from a "small" pelican-sized bird with a nine-foot wingspan to a very large bird, similar to the Charleston specimen, with a wingspan of up to eighteen feet. Other recent Pelagornis finds by members of the CMM Fossil Club include the proximal end of an ulna, found by Wally Ashby at Parker Creek; the proximal end of a femur, found by Donna Richardson at Chancellor's Point; and a femur shaft fragment (possibly from the same individual as Donna's specimen) found by Bob Shaw at Chancellor's Point. The significance of Donna's and Bob's bones is that they are the first evidence of Pelagornis in the St. Mary's Formation. Previously, no Pelagornis remains had been confirmed above the Calvert in Maryland and Virginia, although their presence at Lee Creek in the Yorktown Formation (Pliocene) suggests that they should be found throughout the Miocene. The excitement about pseudodontorns should not cause other fossil birds to be overlooked. Other birds found in the Calvert include gannets, boobies, auks (two species), albatrosses, loons, a few ducks, and a tropicbird, named Heliadornis ashbyi by Dr. Olson. Bones of land birds from the quail/pheasant group have also been found. If you find what you think are fossil bird bones, Dave Bohaska or Dr. Olson at the Smithsonian or Mike Gottfried at CMM would be happy to look at them. If there is sediment inside the bone, don't wash it out as I did, since microfossils in the sediment can help pinpoint the bone's age. If you find bird bones in the cliff, get the assistance of a paleontologist to remove them. Finally, a message for all you BIG TEETH hunters. If you look down and see something that looks like the remains of last week's Kentucky Fried Chicken, don't hesitate to bend down and pick it up. It might just be BIG BIRD~ • 7 • . Y" . ,...,1 ' .'

The next morning they met up with Gene Hartstein, the peripatetic CMM club member who graciously invited other club members to enjoy the hunt of a lifetime at the famous Mazon Creek site (see article in Ninter '92 issue). With five members of the Chicago club to which Gene belongs--Todd McGee, Maurizio Bottoni, Jiangang Sun, Jurek Polanski, and Dave Bergman--Mike and Donna participated in one of the stranger kinds of fossil-hunting imaginable. Gene and Dave launched their somewhat decrepit boats (Dave's wouldn't start and Gene had to bail his all day) into a man-made lake four miles wide, once a coal strip-mine and now the cooling pond for a Com Ed nuke. The group landed on the islands in the lake, former spoil-heaps from the mine, and looked for red pyrite nodules, preferably large and perfectly round but usually small and irregular. The day was fine, the company good, the water unnaturally warm (mostly from the nuke). Occasionally one could find a nodule that was already broken open, but usually they were whole. This means that the hunters wouldn't know what they found until they returned home and completed a potentially endless ritual of soaking the rocks (5 days), blasting them in the freezer for several hours, pouring boiling water over them, and then letting them dry out again (after about 15 rounds of freezing-thawing). The editor has yet to identify those of her nodules that have cracked open, but the most common find is a jellyfish fondly called "the blob" by the local hunters because of its featureless round appearance. (If I ever get mine identified and talk to Mike Batista, perhaps more info on what we found will appear.) The hope is that some turn out to be jawless fish, perfect polychaete worms, and (please) a Tully Monster. At least none of them seems to glow in the dark. Many thanks to Gene and the Chicago club; we hope this bizarre but pleasant event may take place again with more CMM members. LIVERPOOL POIRT: June 13 was an exquisite day for a field trip to this Paleocene site on the Potomac River in Charles County. The group, led by Matt Andrea, included Jim and Jeana Evans; John Rounseville and daughter Melissa; Pam Ogasawara; Stan, LaShea, and Julie Johnson; Elizabeth Slaughter; Rick Flo; Tom McNelis; Vicki Bushong; and Al and Cheryl Snelson. We initially missed the entrance to the park (1.7 miles south of Liverpool Point Road on MD Rte. 224). We got to the river an hour before low tide, but the water was high due to recent rains. Everyone found plenty of Carcharias (Odontaspis) teeth. Matt found a small well-formed Otodus tooth. Vicki found a perfect Thecachampsa tooth and Tom 4 found a small dermal scute. Pam found what seemed to be a sea .turtle phalange and Al found a 2 1/2" sea turtle scute. John found a shark vertebral centrum and Jeana found a 1 1/2" Otodus tooth. We came upon a place where large blocks of marl, loaded with Turritella mortoni casts, had broken off the cliffs. A newer member asked, "How do you extract a Turritella from its matrix?" Another, clearly more experienced fossicker quickly answered, "You unscrew it, of course~" They were actually quite easy to remove from the eroded marl. It was in Turritella territory that Cheryl made the "find of the day"--a complete f1yliobatis den tition, measuring 2 3/4" x 2". About half the group later drove to another Paleocene site near Rosecroft Raceway, south of the Beltway (the bed of a tributary of Henson Creek, described in Glaser's Finding Fossils in ~aryland). There we found many casts of the clam Cucull~a gigant.a. We do not advise others to visit this site in the summer as there was poison ivy everywhere--but we rubbed our exposed body parts with jewelweed as we left and no one was infected. --~att Andrea * * * Summer Sniglefest Whoopsie-Doodle, v.i.
