Continuity mistake: When Jack is killed blood splatters on Dash's sweatshirt and T-shirt. A shot later the blood has changed colour, his T-shirt is spotless and most of the blood on the right side of the sweatshirt is gone.
Continuity mistake: The instructions Evelyn is given had two copies created for the film - the handwriting and circling of the numbers change between shots when she's reading them in the IRS office. Notably the first time we see the instructions it says "don't forget to breath" at the bottom, then later that's changed to "breathe" as it should be. Although interestingly that change is the only one on that version of the notes, implying someone caught the grammatical error during filming and added the "E."
Factual error: Josephine walks away from her father King Louie 14th, after he tells her she has to marry the young Duke Lintillac for his money. When you look at back of Josephine, you can see a zipper in her skirt. King Louie 14th was King from 1643 until his death in 1715. The first zipper was invented was in 1851. The zipper being used as we know it present day was invented in the early 1890s by Whitcomb L. Judson. (00:55:57)
Continuity mistake: After the huge sinkhole appears in front of Bob's Burgers, there are numerous striped safety barriers on the street, and in the following shots the direction of the stripes change to the opposite direction on some of the barriers. (00:11:30)
Continuity mistake: When Owen latches on the parasaurolophus he stops it with a tree trunk. He loses grip on his rope, leaving just a small bit of rope. He then ties a longer piece around the trunk. (00:08:44)
Continuity mistake: When Chloe, Nate, and Sully rest and talk about wine, Sully holds the glass differently between shots. One shot it's by the stem another by the foot/base.
