Fossil Friday – horse metacarpal


One of the joys of paleontology is that every fossil has a story. Through our understanding of anatomy, geology, ecology, and a host of other field, we can often reveal part of that story, and even a relatively small, nondescript fossil takes on a larger meaning. Continue reading

Fossil Friday – horse skull

Among the large animals recovered during the Diamond Valley Lake excavation, fully 1/5  of the specimens came from horses; only bison bones were more common among the large animals.

Reflecting this, there are a number of E. occidentalis skulls in the WSC collections. Continue reading

As with DVL, these have mostly been found during construction projects. The specimen shown above was recovered from The Promenade shopping mall in Temecula. Continue reading
