The freshwater reservoir effect can result in anomalously old radiocarbon ages of samples from lakes and rivers.
Markus Frind, 36, is the founder and CEO of the Vancouver-based Plenty of Fish.
Frind told Business Insider he started Plenty of Fish in 2003 "as a way to improve my résumé." "At the time there was a new programming language called ASP.
The 518 million-year-old fish was about 6cm long, bore a pair of large protruding eyes and small paired nasal capsules (see image, above). It had a stout rod supporting its spine (notochord) enabling strong W-shaped muscle bands to develop along its entire body.
Its ability to swim fast was no doubt a key factor in its success while living in precarious seas inhabited by huge predators such as from the Ediacaran fauna of Australia, dated at 560 million years old.
He has retained complete ownership of the company, which has 75 employees.
"By the time I found out what VCs were, I was already making millions in profit, and I didn't see the need to raise money because I wouldn't know what to do with it," he told Business Insider.
"It was a profitable company, and there was no need to raise money." Plenty of Fish's deal with Match will close by the end of the year.
Frind says Plenty of Fish, which has 90 million registered users and 3.6 million active daily users, was "immediately profitable." In 2008, Frind told The New York Times that his website's net profits were about million a year and that he worked only about 10 hours a week. "It's funny, once you start adding people to the company, the amount of time you have to work goes up," he told Business Insider. I've been working normal hours the past few months." Match Group CEO Sam Yagan said in a statement that he had been interested in Plenty of Fish for more than 10 years.
The surprisingly old ages of the earliest pottery most probably are caused by a freshwater reservoir effect.
