Hainosaurus is now congeneric with Tylosaurus. I guess that means that it's Tylosaurus bernardi now.

www.livescience.com/52650-ichthyosaur-fossils-reexamined.htmlA specimen discovered in the early 1800s has been mislabeled as Ichthyosaurus communis. However, futher study shows that the fossil wasn't Ichyosaurus communis after all and is an entirely new species, named Ichthyosaurus anningae in honor in Anning. Any more fossils that have been mislabled for over 100 years?

'The project began when Dean Lomax, a paleontologist at the University of Manchester, found an ichthyosaur skeleton in the collections of the Doncaster Museum and Art Gallery in the United Kingdom.
An analysis by Lomax and Massare revealed that the 189-million-year-old specimen was a new species of ichthyosaur. For instance, it was considerably smaller in body length than Ichthyosaurus communis and larger than Ichthyosaurus conybeari, the researchers noted. They named it Ichthyosaurus anningae, in honor of Mary Anning, a British fossil collector who, in 1811, found the first ichthyosaur to be scientifically described.
If one museum had a newfound species of ichthyosaur, the researchers wondered, what about other museum collections?
So, they focused on the ichthyosaurs from Street, and located 16 well-preserved partial to nearly complete skeletons from museums and collectors, including the Clarks. An ongoing analysis suggests that many of the specimens were mislabeled, with the group containing at least three, and probably four, ichthyosaur species, Massare said.
Some of the ichthyosaurs belong to two known species groups, she said. Others appear to belong to a species described in the 1800s that some researchers do not consider to be a distinct species, but further analyses will likely clear this up, Massare said.
Finally, one of the ichthyosaurs might be a newly identified species, but more work is needed to say for sure, Massare said.
"What we're finding is, one species that we used to think was extremely variable only looks variable because we were combining a couple of other species," she said. "We're now trying to figure out the boundaries between those different species."
For instance, differences in tooth and forefin shape suggest that these species ate different prey and had different swimming capabilities, the researchers said.
Ichthyosaurus communis, once thought to be widespread in Street, is actually not so common, the researchers said.
"With the recognition of these species, at least seven species of Ichthyosaurus are found in the Lower Jurassic strata [rock layer] of the United Kingdom, making it the most diverse ichthyosaurian genus of that time interval," they wrote in the abstract for their presentation of the unpublished findings at the 75th annual Society of Vertebrate Paleontology conference, held in Dallas in October.'
