A gap in the fence will cause the objective to glitch. You can use the Ranger Team to fix the enclosures, but don't miss any repairs. ![]() Another dinosaur gets into the Allosaurus enclosureĪfter you've built the Arrival point, Control Center, Backup Generator, and Response Facility, you'll be tasked with repairing the broken fences to create enclosures for the Carnotauruses.The Allosaurus bug in the Washington state mission seems to rear its head when: Science Advances 9 (5) doi: 10.1126/sciadv.How to Fix the Jurassic World Evolution 2 Allosaurus Bug Late Pleistocene osseous projectile point from the Manis site, Washington-Mastodon hunting in the Pacific Northwest 13,900 years ago. The study was published in the journal Science Advances. “These sites likely represent the first people and their descendants that entered the Americas at the end of the latest Ice Age.” So there appears to be a cluster of early sites in the Northwestern part of the United States that date from 16,000 to 14,000 years ago that predate Clovis.” “And here we report on the 13,900-year-old Manis site. “It is interesting to note that in Idaho there is the 16,000-years-old Coopers Ferry site, in Oregon is the 14,100-year-old site of Paisley Caves.” They eventually got past the ice sheets that covered Canada and made landfall in the Pacific Northwest.” They took a coastal route along the North Pacific and moved south. “It is looking like the first people that came to the Americas arrived by boat. “The Manis site and others are giving archaeologists some insight,” Professor Waters said. Not much is known about the people who used the Manis projectile point other than they were some of the first Indigenous people to enter the Americas. “This shows that the First Americans made and used bone weapons and likely other types of bone tools.” At the other pre-Clovis site, only stone tools are found.” “What is important about Manis is that it’s the first and only bone tool that dates older than Clovis. “Dating from 13,050 to 12,750 years ago, Clovis spear points have been found in Texas and several other sites across the country.” “At 13,900 years old, the Manis point is 900 years older than projectile points found to be associated with the Clovis people, whose stone tools he has also studied.” This is this the oldest bone projectile point in the Americas and represents the oldest direct evidence of mastodon hunting in the Americas.” “This clearly showed this was the tip of a bone projectile point. “We isolated the bone fragments, printed them out and assembled them,” Professor Waters said.

The Manis mastodon rib with an embedded projectile point: (A) three views of the rib fragment with embedded point (B) close-up views of the embedded point note root staining on the bone and embedded bone point. The genetic study showed that the bone fragments embedded in the rib are from a mastodon. ![]() They isolated all the fragments to show it was the tip of a human-made projectile point (34.5 mm long, 16.9 mm wide, and 5.8 mm thick).Īccording to the team, the fragments became embedded in the rib when the mastodon was alive, as indicated by the visible healing around the site of the wound. ![]() In the new study, Texas A&M University’s Professor Michael Waters and colleagues used high-resolution micro-CT scans and 3D software to study those foreign pieces. Those foreign pieces were interpreted to be the tip of a projectile point that broke apart as it impacted and entered the rib. In addition, the end of a mastodon’s right rib had foreign fragments embedded in it. No stone tools were found at the site, but human interaction with the mastodon was suggested by bones with spiral fractures, flakes removed from a long bone, and bones with cut marks. In the 1970s, archaeologists excavated a single male mastodon from sediments at the base of a kettle pond at the Manis site, Washington.
