Trigrawr

The Trigrawr, an extinct species that once thrived in the tranquil waters of rivers and lakes, is believed to have lived over 100 million years ago, during a time when it was particularly abundant. These fascinating creatures were capable of both aquatic and terrestrial movement, using their specialized legs to traverse the riverbanks in search of prey and other resources. As juveniles, they displayed unique behaviors, including the collection of mushrooms from the lakeside, which they placed on their backs as a form of identification within their species.
This remarkable specimen was first documented by Mason at Glacial Lake Great approximately 90 million years ago. The Trigrawr could grow to an impressive size, ranging from 7.1 to 9 feet in length. Its diet primarily consisted of smaller fish, as well as some river plants, and its ability to chase prey underwater was enhanced by its well-developed legs. I personally encountered one of these creatures while sitting by the riverbank, observing it as it approached a tree to gather mushrooms before returning to the water. This encounter provided the inspiration for the sketch I made of the creature in its juvenile form, offering a glimpse into the life of this extraordinary species.
