This is Machimosaurus, an impressive crocdile-like Jurassic predator from our Evolution Gallery ! 

Machimosaurus is a crocodyliform of the Teleosaur family, which ruled the seas and oceans from the Upper Jurassic to the Early Cretaceous.

 Members of the Teleosaur family were initially more slender, with a much longer snout efficient at catching smaller preys such as fish. However, over time, Machimosaurus evolved to become particularly larger than its relatives, with a slightly shorter snout.  

Semi-aquatic, Machimosaurus was able to venture ashore to hunt. However, this exceptional swimmer was a master of deep-sea hunting. In the water, it used its short legs to steer and to keep balance, while its robust tail allowed Machimosaurus to propel itself. 

Other distinguishing features of this species were its massive skull and long snout. Using its conical, rounded teeth and an overpowering jaw force, Machimosaurus was able to target larger or shelled prey: fish, turtles and other marine reptiles, as well as some overly adventurous terrestrial species had to be especially cautious of this fierce predator. 

Fossils of this 100-million-year-old giant have been discovered in several countries across Europe and Africa. These findings have allowed palaeontologists to separate, to this date, the lineage of Machimosaurus into five probable species. 

One of these, the Machimosaurus rex recovered from a desert in Tunisia in 2016, could be the largest member of this lineage. According to various estimates, this animal could have grown up to more than 7 metres in length, for 3 tonnes: not the kind you'd want to meet in a face-off!

RR Pod E27 Dell Rose - Cultural Receptions of Emanuel Swedenborg: Connecting the Spiritual with the Material This month's topic centers around Emanuel Swedenborg, who was, and still is, an extremely influential figure within the currents of esotericism. Dell Rose begins by giving a short introduction about Swedenborg, and then moves to discuss other aspects of Swedenborg's life and beliefs that led to his eventual 'revelations' about the nature of the spiritual world and free will.  Dell is particularly concerned with the cultural reception of Swedenborg, and he notes that Swedenborg's influence is varied, but overwhelming. This influence is seen in all forms of cultural life from the 19th century onward, in areas such as art, literature, poetry, and music; but also in the political sphere, including public planning, cooperative societies, and women's rights. Dell shares his own research into Charles Augustus Tulk, who was keen to implement Swedenborg's ideas onto social issues, as well as other figures who were also inspired by Swedenborgian thought.

Spending the summer at Camp Arey

By Jonathan Monfiletto

These days, you could still spend the summer along Keuka Lake at Camp Arey – just as youngsters could for nearly four decades from about the turn of the 20th century until the outbreak of World War II. However, with all due respect to the owners and residents of what is nowadays a seasonal vacation community, these summer homes on the lake seem a far cry from the natural science camp of yesteryear.

The Yates County History Center recently heard from a descendant of Dr. Albert Arey, who started the natural science camp. I knew the name of the camp and that it had been a summer camp for boys and girls, but that was about all I knew. I didn’t even know where the camp was located, except that it had been on Keuka Lake. Naturally, for those who know me or at least know my writing, this communication led me to research Camp Arey and learn more about it.

The first thing I learned is Arey, described in our sources as a Rochester science teacher, initially established his camp on the west side of Canandaigua Lake at Tichenor Point – in the town of Canandaigua in Ontario County. A lover of the natural world, the professor started his camp in 1890 so his students would have a place to explore such fields as geology, botany, and taxidermy. As Allison Cooper wrote in a “Time and Again” column in the May 15, 2006 Daily Messenger, “So he leased the plot of land from the Tichenor family, his wife sewed two tents out of sturdy canvas and the Natural Science Camp was born.”

The Natural Science Camp, as it was called then, was set up like a military camp and considered the first of its kind in the United States featuring tent camping. “A bugle horn sounded the wake-up and bedtime calls and at meal time the boys marched two by two to the mess tent,” Cooper wrote. “Dinner was at noon and the campers snacked on barrels of ginger snaps and Smith Butter Crackers, which were made in Canandaigua. They consumed sixty gallons of milk per day.”

The first year, 40 boys showed up to the camp; 15 years later, when Camp Arey prepared to leave Canandaigua Lake and head to new quarters on Keuka Lake, 150 boys per season was the norm. They came from New York City, Albany, Pittsburgh, and Syracuse as well as locales around the Finger Lakes. Their average age was 18. As well as studying science, the boys formed a baseball team and played against teams around the area. They also swam, sailed, and rode horses.

In January 1905, Arey purchased Eggleston’s Point on Keuka Lake in Barrington from Cornwell Bros. through Goodspeed & Miller’s Real Estate Agency and planned to move the camp there. “It is expected that large and permanent buildings will be erected and this point become one of the liveliest places on the Lake,” the Yates County Chronicle asserted on January 25, 1905. On May 5, 1905, the Penn Yan Democrat proclaimed the camp’s new location to be an economic boon for Penn Yan and Yates County – with 150 campers likely making the total camp population 200 including the staff and providing people ready to spend money. A Canandaigua man estimated that area’s merchants’ loss at $30,000 per year when the camp left.

Each year, the camp was to run from July 1 through September 1 – essentially, from the time school let out until it opened again. In 1905, tuition and board for a full term cost $100; shorter periods cost $12 per week. An “athletic tax” of 25 cents per week was also levied on each camper to pay for the equipment and expenses related to the camp’s teams. “While the Science Camp is a big summer school, text books are not every much in evidence,” the Democrat described Camp Arey ahead of its opening. “Nature furnishes many interesting studies, and botany and entomology, geology, taxidermy, etc., are some of the things that will be taught. There will be a shop for electrical demonstrations. The athletic program will consist of track athletics, base ball, basket ball, swimming, boating, riding, and sailing. There will be a dark room for those interested in photography. A dramatic club will be organized the first week of the Camp, and the plan is to produce several plays during the season, and a minstrel show in July. … Large army tents are provided for sleeping quarters. They have wood floors raised from the ground, and a water-proof ‘fly.’ Each tent accommodates three pupils, and has an electric light.”

As the camp prepared to open on Keuka Lake, arrangements were in the works to have the camp’s baseball team play some of its games in Penn Yan. There was also talk of field trips from the camp to Niagara Falls, the Thousand Islands, and Watkins Glen. Visitors were welcome to the camp at any time, through the arrangement of the commandant. All of the coaches and instructors at the camp had college degrees, and some had served in the U.S. military.

Various sources point to the different reasons for Camp Arey’s change in location. More campers meant the camp needed a larger property. Indeed, the Democrat on July 4, 1906 announced the beginning of the camp’s first season on Keuka Lake with 275 boys and young men. At the same time, the Tichenor family’s price to purchase the Canandaigua Lake site was too high for Arey. Keuka Lake offered more land at a cheaper price.

Various sources also provide different dimensions for the camp’s property. An unidentified source states Arey organized the camp on Keuka Lake on 125 acres with 2,000 feet of lake frontage. An outline of Camp Arey’s history put its at 160 acres. Notes left behind by former Yates County Historian Frank Swann list the parcel at 140 acres. The Democrat in 1906 described buildings upon 165 acres of land – an assembly hall large enough to accommodate the entire camp, a 50-by-75 mess hall, an office building, a shop containing the electrical plant, a number of smaller buildings, and the farmhouse, barns, and carriage house.

Camp Arey even had its own post office, to serve the camp as well as locals during the summer season. Campers raised their own vegetables and supplied milk from their dairy. The property eventually expanded to 230 acres when Arey purchased more land for the camp. Though only boys were admitted in early seasons, later on girls were allowed at the camp; boys came for half of the season, and then girls came for the remainder.

Arey himself continued to run the camp until 1912, when he apparently accepted a position in the science department of a girls high school in Brooklyn at twice the salary of his position in Rochester. Moving his family to Brooklyn, Arey sold the camp to his son-in-law and daughter, Andrew and Mildred Fontaine, who operated the property as a girls camp until 1939. The Fontaines in turn sold Camp Arey to Mr. and Mrs. Robert Patin, of Cleveland, Ohio, who continued to oversee the girls camp for a few more years.

The World War II years put a strain on the camp, while living patterns and outlook changed. During the 1940s, the Rockefeller family purchased the property as an executive retreat but apparently kept the Camp Arey name. In the 1950s, there was an effort to make Camp Arey the site of a state park, as at that time there were only two state parks in the Finger Lakes at Taughannock Falls and Cayuga Lake. That effort, however, faced much opposition and failed to come to fruition.

You can still spend your summer at Camp Arey if you so wish. You just won’t be staying in a tent and studying the natural sciences as youngsters once did.

🪸 Meet the Giant Clam (Tridacna gigas)! 🪸

 This impressive mollusc is an inhabitant of the ocean floors. It lives in shallow-sunlit waters near coral reefs.

It’s the largest marine bivalve (same group as mussels and oysters), with a shell that can measure up to 1.4 meters at full maturity, weighing up to 250 kilos! #NatureIsTheGreatestShow

Believe it or not, Giant Clams can “walk”.As juveniles, they move very slowly across the ocean floor to find a spot with the best possible sun exposure.Once in place on the reef, a healthy Giant Clam will live on the spot for up to one hundred years!

They live in symbiosis with billions of Zooxanthellae on their tissue - the same algae that live on corals. The Clam provides the algae with a secure place to live. In turn, the algae absorb solar energy and transform it into sugar and other nutrients the mollusc can consume. They allow the Giant Clam to grow to its full size, even when plankton is scarce.

Giant Clams are recognized by the zig-zag shape of their shell, yet each individual presents a unique colourful pattern on its mantle. The Zooxhanthellae algae mixing with the Giant Clam's natural pigments are to thank for these vibrant colour patterns, while the iridescence is caused by a type of cells that protects them from UV radiation.

The massive size and strange appearance of the clams cost them their reputation. According to legends, these “Killer Clams” waited at the bottom of the sea, shell open, to trap unwary swimmers and swallow them in an instant!

In reality, these clams are harmless to humans: they retract when facing threat and move too slowly anyway, not able to fully close their shells in time.

Humans on the other hand, are the Giant Clam’s biggest threat. Overfishing and illegal poaching almost drove these molluscs to extinction. They are caught for their sought-after mantle tissue (‘meat’) and for their pretty ivory-looking shells used as ornaments or jewels. Today, they are considered a vulnerable species.  

And this is a problem. Giant Clams play a crucial role in their habitat. Their presence, or absence, is a vital indicator of a coral reef's health. [pictures of living Giant Clams through Canva]
