Sea Dwelling Teleosaur Restored and Shown in Exley Science Centre

A 7-foot-extensive extinct marine crocodile has eventually identified a permanent residence on Wesleyan’s campus—exactly 150 decades just after it arrived.

Acknowledged as a Teleosaur (Macrospondylus bollensis), the sea-dwelling lizard lived during the early Jurassic interval, close to 138 million several years ago. A solid was gifted to Wesleyan in 1871 by chemist Orange Judd of the Wesleyan Class of 1847, and the namesake of the University’s Orange Judd Museum of Natural Sciences.

When the museum shut in 1957, a lot more than 900 animal casts, such as the Teleosaur, were being moved into storage in random areas all over campus.


Yu Kai Tan BA/MA ’21 and Andy Tan ’21 restored the Teleosaur’s forged applying far more practical coloring.

In excess of sixty decades later, the Teleosaur solid was found in a big packing situation in the Exley Science Centre penthouse.

“When we unpacked it, it was continue to in acceptable condition. There weren’t lots of cracks, but the soreness on its area was terribly weakened and there were being numerous white places,” mentioned Ellen Thomas, Harold T. Stearns Emerita Professor of Integrative Sciences, Smith Curator of Paleontology of the Joe Webb Peoples Museum of Organic Record.

Thomas, together with Yu Kai Tan BA/MA ’21 and Andy Tan ’21, is spearheading initiatives to restore and exhibit the hundreds of artifacts placed in storage next the purely natural sciences museum’s closing. All restored casts develop into section of Wesleyan’s Joe Webb Peoples Museum.

The restored Teleosaur was at first exhibited together with one more 22-foot-lengthy Teleosaur which—as witnessed in archival photos—was designed into the wall of the museum.

“That massive specimen was wrecked when the wall was blasted to pieces through renovations to the developing but this a person, thankfully, survived,” Yu Kai Tan reported.

The staff began performing on it for the duration of the first stage of COVID-19 lockdowns in March 2020 and finished the restoration in May possibly 2021 with the assist of pupil curators, Cole Goco ’23 and Vivian Gu ’23. They utilized compressed air for the standard dusting of the specimen and consolidated the cracks with archival resin. The missing paint flecks ended up loaded in, then the total specimen was retouched with colors that reflect the coloration of the initial fossil.

“When these casts were being customized-produced for Wesleyan in 1871, they have been alternatively simply painted with available paints at hand. Our restoration with modern-day reversible archival paints generates a greater visible relief and additional accurately displays the initial specimen from which the solid was manufactured,” Tan stated.

To top rated it off, they used many coats of UV-resistant archival varnish to stabilize the paint surface area and shield it from fading.

According to Henry Ward’s Catalogue of Casts of Fossils from 1866, the Teleosaur’s jaws ended up “armed with numerous extensive, slender, sharp-pointed, slightly curved teeth” and the hind limbs were “longer and stronger” than the forelimbs, “which indicated that the T. was a far better swimmer” than the modern-day-working day crocodile and most likely “lived a lot more habitually in the h2o and fewer rarely moved on drylands as its fossil stays have only been discovered in the sedimentary deposits from the seas.”

The Teleosaurus joins various other a short while ago-restored creatures from the Joe Webb Peoples Museum and Collections like a solitary-tusked walrus skull, a restored taxidermied peacock, a Mosasaur marine lizard solid an armadillo-like Glyptodon cast, and the “terrible beast” Deinotherium cast. The casts are applied often for outreach and training.

The primary fossil was found in Baden-Württemberg, Germany in 1828. The forged, which steps 7-toes 2-inches by 2-and-a-fifty percent-feet, initially expense $18. Nowadays, it is still for sale at $1,450.


The Teleosaur forged is prominently displayed inside Exley Science Middle. “Yu Kai and Andy aimed to restore it to the colours of the unique,” Thomas explained. “The fossils are partially replaced by pyrite (‘fool’s gold, iron sulfide), for this reason the golden color.”
