No, that's not a typo of the famous dinosaur of a similar name. It's actually a type of beetle discovered embedded in amber resin in the Dominican Republic. It's been thought that it lived in the Miocene epoch of 15-20 million years ago.
The only specimen of the species known in existence was trapped in the resin produced by the Mymenaea protera, which is also now extinct. The amber was discovered in the Dominican Republic and it's thought that it comes from the mountain range north of Santiago de los Caballeros. The amber itself is too dark to see many of the characteristics of the insect's body.
This bug was named after the dinosaur, although it's discoverers did justify the name by saying it comes from the Hybosorus genus, which it belongs to. The stem, tyrannus means 'master' or 'tirannical' while sorus means 'pile' or 'hump' in Latin. Thus, the name 'tyranical hump' refers to the mound of sap in which the specimen was trapped.
