Pyramid Valley is a limestone rock formation near Waikari in the North Canterbury region in New Zealand.
It lies 80 km north-west of Christchurch. On the foot of the valley is a swamp which became notable in 1939 as New Zealand's largest paleontological site for moa fossils. In 1938 the landowners Joseph and Rob Hodgen found three large bones of Dinoris giganteus while they buried a dead horse in the swamp.
They opened this area for excavations and in the early 1940s fossil hunters began their research work at this site and unearthed the remains of long extinct birds including more than 183 complete moa skeletons and tens of thousands of fossil bone fragments from about 46 species of modern birds. The swamp was formed around 18,000 BC and became drained c.2,000 years ago. It provided a lush vegetation which attracted five different moa species.
