Here's a thinking process:

1. **Analyze User Input:**
- **Role:** Frank, excited, passionate tech-savvy news curator on "Evil Source" community forums.
- **Task:** Rewrite the provided article as a FULL, in-depth forum post.
- **Critical Rules:**
- 1 to 3 PARAGRAPHS (minimum 4 sentences each, maximum 3 paragraphs total)
- Write the ENTIRE story - include every detail, fact, insight
- EXCITING, casual, direct forum style (like telling friends about something mind-blowing)
- Add own commentary, opinions, reactions throughout
- Use line breaks between paragraphs
- Include ALL key information: who, what, when, where, why, how
- Include specs, prices, dates, names
- Reference additional source links naturally if provided
- End with 'Source: <original URL>'
- Do NOT write a headline or use markdown headers
- NEVER write less than one full paragraph
- **Input Article:** About Sotheby's T. rex auction ("Gus"), concerns about private collectors vs. museums, history since 1997 Sue sale, prices, paleontologist opinions, scientific concerns (excavation documentation, CT scanning, marketing hype vs. evidence), specific details about Gus (67M years old, 183 bones, 61% complete, South Dakota ranch, mounted in custom steel armature, bite mark debate).
- **Original URL:** https://arstechnica.com/science/2026/07/sothebys-big-t-rex-auction-raises-concerns-hype-and-wealth-are-upending-science/
- **Additional Sources in Knowledge:** None explicitly provided as links, but the knowledge block has some C/C++ headers/files. They're not directly relevant to the article content, so I'll just reference the main URL and maybe add a note if needed, but the prompt says "If additional source links are provided, reference them naturally in your post." Since none are explicitly provided as URLs in the prompt beyond the original, I'll stick to the original URL at the end.

Wait, the prompt says "If additional source links are provided, reference them naturally in your post." The knowledge block has some C headers but no extra URLs. I'll just follow the rule strictly.

2. **Deconstruct the Article for Key Details:**
- **Event:** Sotheby's opened live bidding on July 14, 2026, on assorted fossils.
- **Star Lot:** Lot 20, "Gus" - a 67-million-year-old T. rex skeleton.
- **Specs:** ~183 fossil bone elements, ~61% complete by bone count, discovered on a ranch in South Dakota, mounted in a custom steel armature with replicas of missing bones, posed in hot pursuit.
- **Expected Price:** Up to $30 million.
- **Context/History:** Trend started in 1997 with Sotheby's auction of "Sue" for ~$8.4 million. Sue went to Field Museum in Chicago. Court cases clarified US landowners own fossils.
- **Key People:**
- Cassandra Hatton (Sotheby's vice chairman/head of science & natural history)
- Thomas Holtz (University of Maryland tyrannosaur specialist)
- Dan O'Dowd (tech entrepreneur, owns T. rex "Samson")
- Ken Griffin (hedge fund billionaire, bought Stegosaurus "Apex" in 2024 for $44.6M)
- Stuart Sumida (paleontologist at CSU San Bernardino)
- Kate Wong (author, WIRED.com, Jul 15, 2026)
- **Trends/Concerns:** Private collectors outbidding museums. More T. rex fossils in private collections than public trusts (2025 study). 2024 sale of juvenile Ceratosaurus for $30.5M to anonymous buyer.
- **Scientific Pushback:** Auction houses say sales rescue fossils from erosion and help with excavation/prep. Paleontologists argue commercial excavation lacks geological context documentation. Mounting for display hinders CT imaging. Marketing hype can override evidence (e.g., Sotheby's claims bite marks on Gus, but Sumida says they're perfectly round/smooth-edged holes, likely not bite marks).
- **Quote from Hatton:** "Before Sue was sold, there were no laws about who owned fossils. There was no value truly ascribed to them."
- **Quote from Sumida (implied):**
